Known Limitations (10)Chapter 1.IntroductionThis table introduces important terms for understanding this document:The DPA EU management tool can run either on the host machine or on the target DPU and allows users to manage the DPA's EUs which are the basic resource of the DPA. TheIntroductiontool enables the resource control of EUs to optimize computation resources usage of the DPA before using DOCA FlexIO SDK API.Without EU allocation, a DPA software thread would lack access to the hardware pipeline/CPU time resource, and consequently not be able to execute. dpaeumgmt serves the following main usages:‣Running a DPA software thread with strict affinity on a DPA EU (i.e., running a DPA thread using only the specific preselected EU). For this purpose, dpaeumgmt provides an option to query the maximum EU ID allowed to use.‣Allowing a DPA software thread to run over a DPA EU from a group of EUs:‣Once a EU group is created, it is allocated a subset of EUs.‣dpaeumgmt provides an ID to the created group which can be used to run DPA applications with group affinity where the affinity ID would be the same as thatgroup's ID.‣EU partition management - the ability to manage EU partitions.When the software stack wishes to run a DPA thread with group affinity type, one of the available EUs from the group's collection is used for the execution.Note: A DPA thread may execute if and only if there is an available EU for it.Chapter 2.Execution Unit ObjectsUpon boot, a default EU partition is automatically created. The default EU partition possesses all the system's EUs. The DPA partition manager function is the only function that belongs to it and can therefore control the entire resources of the system.When running a DPA thread with none affinity, the EU chosen for the DPA thread to run with comes from the partition's pool of EUs. Namely, from the EUs belonging only to the DPA device's current partition which were not assigned to any EU groups (on the current partition). If the aforementioned group of EUs (i.e., the partition's default EU group) is empty, the DPA thread would fail to run with none affinity.Chapter 3.dpaeumgmt Commandsdpaeumgmt enables users to create, destroy, and query EU objects.Note: dpaeumgmt tool must run with root privileges and users must execute sudo mststart before using it.Top-level dpaeumgmt command syntax:Usage: dpaeumgmt {help|version|eu_group|partition}Type "./dpaeumgmt help"for detailed help3.1. General Commands‣Print basic usage information for the tool:dpaeumgmt -h‣Print a detailed help menu of the tool's commands:dpaeumgmt help‣Print version information:dpaeumgmt version3.2. Execution Unit Group Commands The commands listed in the following subsections are used to configure EU groups. 3.2.1. EU Group Command Flags and ArgumentsThe following table lists the flags relevant for eu_group commands. Arguments for the flags must be used within quotes (if more than one) and without extra spaces.3.2.2. Info EU GroupPrint information on the relevant DPA resources for the EU groups:dpaeumgmt eu_group info --dpa_device <device>Example:$ sudo ./dpaeumgmt eu_group info -d mlx5_0Max number of DPA EU groups: 15Max number of DPA EUs in one DPA EU group: 190Max DPA EU number available to use: 190Max EU group name length is 15 chars3.2.3. Create EU GroupCreate an EU group with the specified name on the provided device's partition. The EUs indicated by the range are taken from the DPA device's EU partition.dpaeumgmt eu_group create --dpa_device <device> --name_group <name> --range_eus<range>Example:$ sudo ./dpaeumgmt eu_group create -d mlx5_0 -n "HG hello world1" -r "6-8,16,55,70" Group created successfully-EU group ID: 1EU group name: HG hello worldMember EUs are: 6,7,8,16,55,70Note: After successfully creating an EU group, users can run a DPA thread using groupaffinity with the affinity type set to the group's ID.3.2.4. Destroy EU GroupDestroy a EU group that exists on the device's partition with either the provided group name or ID.dpaeumgmt eu_group destroy --dpa_device <device> [--name_group <name> | --id_group <id>]Example:$ sudo ./dpaeumgmt eu_group destroy -d mlx5_0 -g 1Group with group id: 1, was destroyed successfully3.2.5. Query EU GroupQuery EU groups residing on the provided device's partition. If one of the optional parameters is used, the command only queries the specific group and prints it if it exists: dpaeumgmt eu_group query --dpa_device <device> [--name_group <name> | --id_group<id>]Example:$ sudo ./dpaeumgmt eu_group query -d mlx5_01) EU group ID: 1EU group name: HG hello worldMember EUs are: 6,7,8,16,55,70In total there are 1 EU groups configured.More options:$ sudo ./dpaeumgmt eu_group query -d mlx5_0 -n "HG hello world"$ sudo ./dpaeumgmt eu_group query -d mlx5_0 -g 13.2.6. Apply EU GroupApply the EU groups provided in the file on the device's partition:dpaeumgmt eu_group apply --dpa_device <device> --file_groups <file>File format example:{"eu_groups": [{ "name": "hg1", "range": "178-180"},{ "name": "hg2", "range": "2-10"}]}Note: The command removes all the previous EU groups defined on the EU partition thatthe DPA device belongs to and applies the ones from the file.Example:$ sudo ./dpaeumgmt eu_group apply -d mlx5_0 --file_groups example.json1) EU group ID: 1EU group name: hg1Member EUs are: 178,179,1801) EU group ID: 2EU group name: hg2Member EUs are: 2,3,4,5,6,7,8,9,10In total there are 2 EU groups configured.3.3. EU Partition CommandsThe commands listed in the following subsections are used to configure EU partitions.3.3.1. EU Partition Command Flags andArgumentsThe following table lists the flags relevant for EU partition commands. Arguments for the flags must be used within quotes (if more than one) and without extra spaces.3.3.2. Info EU PartitionPrint the relevant DPA resources of the EU partitions:dpaeumgmt partition info --dpa_device <device>Example:$ sudo ./dpaeumgmt partition info -d mlx5_0Max number of DPA EU partitions: 15Max number of VHCAs associated with a single partition: 32Max number of DPA EU groups: 15Note- an allocation of a partition consumes from the number of DPA EU *groups*available to createMax DPA EU number available to use: 1903.3.3. Create EU PartitionCreate an EU partition on the DPA device:dpaeumgmt partition create --dpa_device <device> --vhca_list <id_list> --range_eus <range> --max_num_eu_group <max_num>Example:$ sudo ./dpaeumgmt partition create -d mlx5_0 -v 1 -r 10-20 -m 2Partition created successfully-EU Partition ID: 1Maximal number of groups: 2The partition has a total of 1 associated VHCA IDs, namely: 1Partition's member EUs are: 10,11,12,13,14,15,16,17,18,19,203.3.4. Destroy EU PartitionDestroy an EU partition that exists on the device's partition:dpaeumgmt partition destroy --dpa_device <device> --id_partition <id> Example:$ sudo ./dpaeumgmt partition destroy -d mlx5_0 -p 1Partition with partition id: 1, was destroyed successfully3.3.5. Query EU PartitionQuery EU partitions that reside on the provided device's partition and print out the partition if it exists:dpaeumgmt partition query --dpa_device <device> [--id_partition <id>] Example:$ sudo ./dpaeumgmt partition query -d mlx5_0 -p 1EU Partition ID: 1Maximal number of groups: 2The partition has a total of 1 associated VHCA IDs, namely: 1Partition's member EUs are: 10,11,12,13,14,15,16,17,18,19,20More options:$ sudo ./dpaeumgmt partition query -d mlx5_0Chapter 4.vHCAs and PartitionsThe following diagram illustrates the ownership and control of a partition by a vHCA and also which vHCAs have claim to (i.e., can use) a partition.Chapter 5.Known Limitations‣Currently, dpaeumgmt is only supported on the DPU not the host‣dpaeumgmt should run before creating a DPA process so all resources are configured ahead of time‣Running the tool over a device with an existing DPA process results in failure‣The EU group name assigned by the user must be unique for every EU group on a specific partition or the EU group create command fails‣The creation of an EU partition consumes from the number of EU groups allowed on the vHCA's partition it is created on:‣ 1 group for the partition itself due to a default group created for each partition ‣<max_num> of groups which is the user's input provided upon partition creation ‣Creating groups or running DPA threads in general (with any affinity) on interfaces other than ECPF, requires a configuration of a valid partition for the specific vHCA ‣Only the default partition is exposed to the real EU numbers, all other partitions the user creates use virtual EUs‣For example, if a user creates a partition with the range of EUs 20-40, querying the partition info from one of its virtual HCAs (vHCAs) would display EUs from0-20. Therefore, the EU whose real number is 39 in this example would correspond to the virtual EU number 19.‣Group IDs on a non-default partition are virtual.‣Different partitions can have completely distinct groups, even if they have the same ID.‣The affinity ID parameter, specified on the FlexIO API, can distinguish between the groups according to the vHCA and application it is running on.‣vHCA ID overlap is not allowed on EU partitions‣It is not possible to query vHCA IDs with dpaeumgmt, these are assumed to be known by the user beforehand‣Partition destruction fails if there are EU objects that exist on that partition‣It is not possible to know which EU has been chosen to run on‣Every vHCA sees the partition it belongs to, and its resources, as the entire world. It only sees:Known Limitations‣Groups and partitions it created‣The number of EUs it was given‣The max_num_eu_group of the partition it belongs to‣No guarantee regarding EU group ID that will be given on group creation‣The default groups (of every partition) cannot be managed by the user‣The EU numbers available are between 0 and the max DPA EU number available to use minus 1 (the upper limit can be queried using the info command specified above)‣dpaeumgmt does not support virtual functions (VFs)‣It is not possible to create partitions on other vHCAs other than the DPA partition manager function‣There are at most 16 hardware EU group entitiesNoticeThis document is provided for information purposes only and shall not be regarded as a warranty of a certain functionality, condition, or quality of a product.

The specialized personnel must be familiar with the installation and operation of electrical and pneumatic control systems.3Further informationAccessories è /catalogue.4ServiceContact your regional Festo contact person if you have technical questions è .5Product overviewThe product is a combination of a DPA pressure booster and a CRVZS air reservoir. The air reservoir is filled to network pressure continuously via a bypass with check valve. Two pressure gauges are there to monitor supply and outlet pressure.5.1FunctionA pneumatic valve conducts the inlet pressure, alternately into two compression chambers. The compression chambers generate an outlet pressure up to max. double the value of the inlet pressure. This increased outlet pressure is stored in the CRVZS and is available for compressed air applications.5.1.1Operational principleThe air pressure is increased by a pressure ratio via a double piston.5.1.2Switching functionAs soon as the inlet pressure is switched on at pneumatic connection P1, the DPA starts automatically. When the set outlet pressure is reached, the pressure booster stops operating, but restarts automatically as soon as the outlet pressure drops due to application operation.6Festo – DPA-CRVZS – 2017-07a EnglishDPA-CRVZSFesto – DPA-CRVZS – 2017-07a English 75.2Design5.2.1Product design1CRVZS air reservoir2CRVZS connecting tubing to DPA pressure booster (connection 2)3DPA pressure booster4Adapter plate with silencers 5Profile plate6Pneumatic valve with manual override7Pressure displays for ports P1 and P28Rotary knob on the pressure regulator for port P29Pneumatic port P1 (inlet)aJ BypassaAPneumatic connection P2 (outlet) with coupling socket KD4Fig. 1DPA-CRVZS8Festo – DPA-CRVZS – 2017-07a English6TransportWarningLoads which suddenly fall down may cause injury to people.Take the product's weight into account. Depending on the design, the DPA-CRVZS weighs up to 30 kg.Do not use the rotary knob on the pressure regulator 8 as a transport support.The weight of the product may cause the rotary knob to detach from its support.7StorageRemove the packing with the exception of the adhesive labels on the supply ports (to prevent dirt from entering).The packaging is intended for recycling (exception: oil paper = residual waste).DPA-CRVZS8Mounting8.1PreparationBefore fitting:Remove the rubber buffers from the bottom of the profile plate.Switch off the complete system to depressurise it.8.2Mechanical installationNoteThe manufacturing process leaves a layer of oxide on the inside of the reservoir caps ofthe air reservoir CRVZS.For sensitive applications, use suitable filters between the air reservoir CRVZS and other downstream-switched pneumatic devices.8.2.1AlignmentEnsure that the screwing points for the profile plate are on the same level.With pressure booster combinations DPA-CRVZS5/10/20:Align the product so that the condensate drain faces downwards.8.2.2MountingSecure product by the grooves in the profile plate on the system or on the machine frame.Mounting attachments from the profile kit system 5 for machine stands–Slot nuts IPM-VN-05-15/M5-ST–Cover caps for profile plate IPM-AN-05-20X40-PAThis accessory can be obtained from Festo Sales, quoting Mechanical Components.Additional accessories:–M5 machine screws–Strength: min. 8.8–Screw length: Frame thickness + 6 mm screw-in depth–Tightening torque: 5 Nm ± 10 %Festo – DPA-CRVZS – 2017-07a English9DPA-CRVZS10Festo – DPA-CRVZS – 2017-07a English8.3Pneumatic installationNoteHigh pressure differential between ports P1 and P2 causes high air consumption by the product.Limit network pressure at port P1 to 8 bar without additional pressure regulators. Use short lines at port P1.Connect hoses and plug connections to pneumatic ports P1 and P2.For port P2 use a KS4 coupling connector.Exhausting is performed by the pressure regulator.Fig. 2P2P1–Controller failsafe LRVS-D-MINI, LRVS-D-MIDI –Padlock LRVS-DAccessories (è /catalogue)When using a pressure-buildup valve in the system 1.Connect a 3-way on/off valve HE-…-D or HEE-…-D at the inlet side before port P1 between pressure buildup valve and pressure booster.2.Connect a 3-way on/off valve HE-…-D or HEE-…-D at the outlet side after port P2.Exhausting is performed by the pressure regulator.Fig. 3P2P1With pressure booster combinations DPA-…-CRVZS10/20:1.Connect a 3-way HE-…-D or HEE-…-D on/off valve at the inlet side before port P1.2.Connect a 3-way on/off valve HE-…-D or HEE-…-D at the outlet side after port P2.3.Connect a third 3-way HE-…-D or HEE-…-D on/off valve between the DPA pressure booster and the CRVZS air reservoir.This enables larger reservoir volumes to be exhausted more rapidly.Fig. 4P2P1DPA-CRVZSFesto – DPA-CRVZS – 2017-07a English 119CommissioningWarningThe sudden escape of compressed air can cause injury to human beings. Make sure that the connections P1 and P2 are connected.NoteHigh pressure forces can damage equipment switched downstream.Only use fittings designed for the maximum achievable outlet pressure of 16 bar.Vibrations can cause signs of fatigue in materials and can reduce the endurance strength of DPA-CRVZS pressure booster combinations and mounting components. Protect the device against mechanical vibrations.Coupling and uncoupling of compressed air outletConnect hose KS4 to port P2. (accessories è /catalogue)Set outlet pressure to max. 10 bar to reduce the amount of force required.WarningPressurized compressed air lines can cause whipping effects. Metal screw connectors at the ends of tubing can therefore cause serious injury. Grip the hose when unfastening the hose sleeve.9.1Switching onWhen using the product without 3-way on/off valves (è Fig. 2): Apply compressed air to port P1.When using the product with 3-way on/off valves (è Fig. 3, Fig. 4):1.To fill the CRVZS air reservoir, open the 3-way on/off valve between the DPA pressure booster and the CRVZS air reservoir (è Fig. 4) and leave open at all times during operation.2.Open the 3-way on/off valve at port P1 (inlet).3.Open the 3-way on/off valve at port P2 (outlet).DPA-CRVZS12Festo – DPA-CRVZS – 2017-07a English9.2Setting the outlet pressureThe rotary knob on the pressure regulator is used for setting (è Fig. 1 8).Regulator lock (only DPA-63-10-… and DPA-100-10-…)–Pushing:Rotary knob locked –Pulling:Rotary knob unlocked1.Unlock the rotary knob (only DPA-63-10-… and DPA-100-10-…).2.Turn the rotary knob clockwise as far as stop (delivery condition).3.Apply inlet pressure to port P1.NoteDo not exceed the maximum permitted pressure.

AtlasIED DPA 系列电源放大器 Site Manager 参考指南说明书
DPA Amplifier Site Manager Reference GuideDPA Amplifier Site Manager, Reference GuideThe AtlasIED DPA amplifier Site Manager is a Windows based software application that is designed to locate, communicate with, and monitor DPA Series amplifiers connected to a Local Area Network (LAN). DPA Series amplifiers feature an onboard web browser interface to allow access to the amplifier’s configuration, control functions, and DSP settings. The DPA Site Manager is a quick and simple way to discover the IP addresses of multiple DPA Series amplifiers within a LAN. Once the IP addresses are located, access to a specific DPA amplifier web interface is a click away.The DPA Site Manager can also perform other functions including remote monitoring of network status, fault condition status, and fault reporting via email, Input / Output status, amplifier configuration file management, firmware updating, and weekly scheduler for DPA amplifier energy-saving power management. Note: the DPA102PM model has limited functions with the DPA Site Manager software. Refer to “DPA102PM Limitation Notes” at the end of this document for details.Features• DPA Amplifier IP Discovery• Works with Multiple DPA Amplifiers• Network Status Remote Monitoring• DPA Amplifier Status: Fault, Sleep / APD Mode, Active• Input / Output Status: Active and Mute• Two Level Fault Reporting Email Configuration• DPA Amplifier Design File / Configuration File Transfer Management• Firmware Update Management• Scheduler 24/7 for DPA Amplifier Energy Saving Power ManagementInstallation of Software1. Download the DPA Site Manager software from the AtlasIED web page, /dpa-series.2. Unzip the file, open the folder, and click on the file “AtlasIED DPA Amplifier Site Manager”.3. Follow the installation wizard prompts.Note:The program requires Java JRE 1.8 to be installed on the system. The Java JRE 1.8 comes bundled with the installer package and the user can follow on screen instructions to install.Getting Started1. Connect all DPA amplifiers to the same network as the computer running the DPA Site Manager software. Make sure the amplifiers are plugged inand the Ethernet port on the rear of the amplifier shows traffic with both the green & yellow LEDs blinking.2. Open the DPA Site Manager software and click on the discover tab. A timer wheel will appear indicating an IP search is in progress. A list of DPAAmplifiers along with their IP and MAC addresses will appear.DPA Site Manger Features & Description1. Discover T ab – When first using the DPA Site Manager, no amplifiers will be listed. Click on the Discover tab and the process of Auto discovery will start. The software will search the LAN for any DPA amplifiers active within the LAN. Firewall and network configuration settings created by the network administrator may cause issues with discovery. Contact the facility IT department should this issue arise. Note for support: The application uses UDP to search for the amplifiers. Some networks may block all UDP traffic. If the user cannot find an amplifier, AtlasIED suggests using a direct Ethernet connection from the computer to the amplifier. This indicates that the network may be at fault. Refer to the DPA owners manual for Direct Connection instructions.If no amplifier is shown, the user will have to disable all firewalls/antivirus programs in order to try again. If an amplifier does show in a direct connection, but not when it is connected to a router, then most likely it is the network blocking the programs access to the network. In this case,the user must request assistance from a network administrator.2. Discovery In Process Indicator – This rotating icon indicates the IP Discovery search is in progress. When the search is finished, the icon willdisappear.3. Model Number – After a DPA amplifier is discovered, a list will be generated showing all models connected and found on that network. This field is the DPA Amplifier model number. Right click on the model and select OPEN or DELETE. Selecting OPEN will open the DPA amplifier’s onboard web page. Clicking DELETE will remove the amplifier from the list. The web page can be also selected by double clicking the amplifier in the table.4. IP Address – This is the Internet Protocol numerical label that is assigned to each device. This address is assigned to the DPA amplifier from aDHCP Server when the amplifier is in DHCP mode or by a technician that has assigned the unit a static IP address.5. Host Name – This is the name of the DPA Amplifier that was assigned. This name may not match the amplifier model number if it has been changed so that it can be identified easier on the LAN. It is common to change the HOST name when there are multiple units that are the same model on the same LAN. For example, in a school with 30 classrooms that each has a DPA602, the amplifiers could be named after eachclassroom number, RM222.34518215221711920141621678910111213DPA Site Manger Features & Description6. MAC Address – This is the physical address of the amplifier when the product was made. It cannot be changed.7. Configuration File Upload– A configuration file is a file with specific data pertaining to a DPA amplifier that contains all the Level settings, routing,and EQ. This works in conjunction with #19 Configuration File Transfer. This box needs to be checked for the amplifier to execute a file to be uploaded from the computer to the amplifier or downloaded from the amplifier to the computer.8. Firmware Upload – There are times when a new feature is issued or a bug is discovered in the software. This box needs to be checked for thefirmware files to be uploaded from the computer to the amplifier. Multiple DPA amplifiers of the same model can have firmware updated at the same time. This works in conjunction with #20 Firmware File Transfer section.9. Scheduler – A DPA amplifier can be automatically turned On or Off via the DPA Site Manager using the scheduler to send the commands to theamplifier. This box needs to be checked if that specific amplifier is to be assigned to the schedule. Refer to section #22 Settings – line F- Scheduler - for information on setting days and times. Note: After setting the schedule in the Setting / Scheduler page, selct the amplifer that will follow the created schedule.10. IP Status – This indicator informs the user if the DPA amplifier has a connection to the network. Green means the amplifier and the DPA SiteManager software are communicating and Red indicates there is no connection or communication. A notification email can be sent if the connection is lost. Refer to section #22 Settings – line C – Email Settings – to set up an email warning notification.11. Amplifier Status – This indicator has three color references to indicate the status of the amplifier.• Green – Indicates the amplifier is working properly.• Y ellow - Indicates the amplifier is in Sleep Mode or APD (Auto Power Down) mode. APD Mode is activated when the amplifier does not detect an audio signal for 30 minutes and will automatically enter into a lower power consumption state to meet Energy Star® standbystandards. When the amplifier detects a signal above 1mV, the amplifier will return to active idle status. The indicator will go from Y ellow to Green. Refer to the DPA Owner’s manual for details on the DPA’s three power states.• Red – Indicates an amplifier’s channel has a fault condition or the amplifier has lost AC Mains power. If the amplifier loses AC Mains power the IP Status indicator will also be Red. Note: A fault message can be sent, refer to section #22Settings – line C – Email Settings – to set up an email warning notification.12. Input Channel Status – This indicator has three color references to indicate the status of the amplifier inputs.• Green – Indicates the Input is on and ready.• Red – Indicates the Input is muted.• Gray – Indicates the inputs 5-8 are not enabled. Note: For the model DPA102PM refer to the section “DPA102PM Limitation Notes”13. Output Channel Status – This indicator has three color references to indicate the status of the amplifier Outputs.• Green – Indicates the Output is on and ready.• Red – Indicates the Output is muted.• Gray – Indicates this feature is not applicable for the DPA102PM. Note: For the model DPA102PM refer to the section “DPA102PM Limitation Notes”DPA Site Manger Features & Description14.

In each case, the relevant points must be selected, supplemented, andassessed on a product or process-specific basis.When the various process levels are evaluated with respect to part B (series production), each process level must be specified.In this questionnaire, questions or comments specific to Daimler AG are indicated accordingly.Key:- Additional Daimler requirements vis-à-vis VDA 6.3 question: CorpoS bold- Special Daimler question: question no. is CorpoS bold italics (e.g.6.2.8)- Question with logistical aspects: (L)i.e. must be answered in conjunction with a logistics expert.2 Part A: Product Development ProcessProduct/process development in the product creation process is based on the four phases ofthe product quality planning cycle (plan/implement/analyze/improve). Interdisciplinarycollaboration and systematic procedures at all stages of product development are essential for fulfilling all the requirements regarding production start-up for a product.At the start of the product development process, all those involved must be aware of thecustomer requirements, market trends, standards, and laws, which must be systematicallyintegrated in the core and supporting processes, taking into account any changes made during product development.Reviews must be conducted at regular intervals to monitor compliance with the definedprocesses and targets since any non-conformities or change requirements can affect thetargets.Correct and systematic risk analysis and evaluation methods in the product developmentprocess ensure that non-conformities and required corrective measures can be identified ingood time. These are a key factor in optimizing and limiting costs.All employees involved in a project are subject to stringent requirements regardingqualifications and performance. They must work in a systematic manner at all stages of product development to ensure that all customer requirements are fulfilled and series production canbegin with the required high level of quality.Note: The VDA publication volumes 1, 2, 3, 4.1, 4.2, 4.3, 6.1, 6.2, 6.4, and 7 are also valid and must be taken into account.2.1 Product Development (Design)2.1.1 M1: Planning Product DevelopmentThe internal planning objectives for a new product, which are based on customer requirements and the relevant legislation, must be defined during the quotation phase. Once the order hasbeen received, these are then specified in greater detail and included in a product development plan.In the product development plan, all the required tasks must be specified and assignedachievable goals and deadlines.The requirements for a product are often more stringent than the customer requirements andmust be analyzed and specified in detail by the organizational/functional units.

A preset, in the context of the DPA amplifiers, is a combination of amplifier configuration and DSP processing; recalling a preset can change the output routing and wiring and/or any DSP processing.Preset CreationA preset can be created in two ways. The first is to modify an existing preset, then save this as a new one; the second is to use the Preset Wizard to create a preset from scratch.Preset izardThe Preset Wizard simplifies the preset creation process, and allows the user to create a preset from the ground up. The Wizard provides a mechanism for the user to select his desired power and load. Based on these selections, the best amplifier configuration is selected and the user is then allowed to select and assign loudspeakers to each output.To start the Preset Wizard: HOME > PRESETS > PRESET IZARD > ENTER STEP 1 — About the Preset WizardHOME > PRESETS > PRESET WIZARD > ENTER > ENTER STEP 2 — Adjust impedance and powerTo confirm, pressAdjust ImpedanceDefault = 8 ΩDefault = min. for ampENTERAdjust Power — Figure 14 —Modes:A B = Separate Channels A+B = Bridge Mode AB = Parallel ModeSTEP 3 — Select output channel for speaker assignmentSTEP 4 — Select speaker type for channelTo edit speaker, pressScroll to select a speaker modelTo confirm, pressScroll to select (Band, Filter)To edit, pressTurn to adjust parameterTo confirm, pressScroll to select ASSIGNTo assign the speaker to the output channel, pressBand and filter selections are based on the speaker you select.You must select a loudspeaker before selecting band and filter.STEP 5 — Save Wizard PresetScroll to the Save screenTo name and save the preset,Complete steps 1 thru 3 under “To Save a New User Preset”To edit User Preset number, pressENTERSTEP 6 — Name the loudspeaker profileIndicates editing Indicates “Speaker Profile Name” is selectedUp to 21 characters A - Z / a - z / 0 - 9 / _ / - / spaceTo add Speaker Profile Name, press Enter .Scroll to desired letter position; press Enter .Turn to select desired character; press Enter .When finished, scroll to SAVE; press Enter .Presets can be modified and saved using the Save Preset menu.

References (13)Chapter 1.IntrodutionThis example shows how the MPI all-to-all collective can be accelerated on the DPA. In an MPI collective, all processes in the same job call the collective routine.Given a communicator of n ranks, the example performs a collective operation in which all the processes send and receive the same amount of data from all the processes (hence all-to-all).This document describes how to run the all-to-all example using DOCA DPA.Chapter 2.System DesignAll-to-all is a message passing interface (MPI) method. MPI is a standardized and portable message-passing standard designed to function on parallel computing architectures. An MPI program is one where several processes run in parallel.Each process in the diagram divides its local sendbuf into n blocks (4 in this example), each containing sendcount (4 in this example) elements. Process i sends the k-th block of its local sendbuf to process k which places the data in the i-th block of its local recvbuf.Implementing the all-to-all method using DOCA DPA offloads the copying of the elements from the srcbuf to the recvbufs to the DPA, and leaves the CPU free to perform other computations.Chapter 3.Application ArchitectureThe following diagram describes the differences between the host-based all-to-all and DPA all-to-all.‣In DPA all-to-all, DPA threads perform the all-to-all and the CPU is free to do other computations‣In host-based all-to-all, the CPU must still perform the all-to-all at some point and is not completely free for other computationsChapter 4.DOCA LibrariesThis application leverages the following DOCA driver:‣DPA libraryChapter 5.Configuration FlowThis section lists the application's configuration flow which includes different FlexIO functions and wrappers.1.Initialize MPI.MPI_Init(&argc, &argv);2.Parse application argument.a).Initialize arg parser resources and register DOCA general parameters.doca_argp_init();b).Register the application's parameters.register_all_to_all_params();c).Parse the arguments.doca_argp_start();i.The msgsize parameter is the size of the sendbuf and recvbuf (in bytes). Itmust be in multiples of an integer and at least the number of processes timesan integer size.ii.The devices_param parameter is the names of the InfiniBand devices to use (must support DPA). It can include up to two devices names.d).Only let the first process (of rank 0) parse the parameters to then broadcastthem to the rest of the processes.3.Check and prepare the needed resources for the all_to_all call:‣Check the number of processes (maximum is 16).‣Check the msgsize. It must be in multiples of integer size and at least the number of processes times integer size.‣Allocate the sendbuf and recvbuf according to msgsize.4.Prepare the resources required to perform the all-to-all method using DOCA DPA:a).Initialize DOCA DPA context:i.Open DOCA DPA device (DOCA device that supports DPA).open_dpa_device();ii.Create DOCA DPA context using the opened device.doca_dpa_create();b).Create the required events for the all-to-all: One completion event for the kernellaunch (wait location CPU and update location DPA) and kernel events (waitlocation remote and update location DPA) as the number of processes.create_dpa_a2a_events() {doca_dpa_event_create(doca_dpa, DOCA_DPA_EVENT_ACCESS_DPA,DOCA_DPA_EVENT_ACCESS_CPU, DOCA_DPA_EVENT_WAIT_DEFAULT, &comp_event, 0);for (i = 0; i < resources->num_ranks; i++)doca_dpa_event_create(doca_dpa, DOCA_DPA_EVENT_ACCESS_REMOTE,DOCA_DPA_EVENT_ACCESS_DPA, DOCA_DPA_EVENT_WAIT_DEFAULT, &(kernel_events[i]),0);}c).Create DOCA DPA worker (for the endpoints).doca_dpa_worker_create();d).Prepare DOCA DPA endpoints:i.Create DOCA DPA endpoints as the number of processes/ranks.for (i = 0; i < resources->num_ranks; i++)doca_dpa_ep_create();ii.Connect the local process' endpoints to the other processes' endpoints.connect_dpa_a2a_endpoints();iii.Export the endpoints to DOCA DPA device endpoints (so they can be used by the DPA) and copy them to DPA heap memory.for (int i = 0; i < resources->num_ranks; i++) {result = doca_dpa_ep_dev_export();doca_dpa_mem_alloc();doca_dpa_h2d_memcpy();}e).Prepare the memory required to perform the all-to-all method using DOCA DPA.This includes creating memory handlers for the sendbuf and recvbuf, getting the other processes' recvbufs handlers, and copying these memory handlers and their remote keys and the events' handlers to the DPA heap memory.prepare_dpa_a2a_memory();unch the alltoall_kernel using DOCA DPA kernel launch with all the requiredparameters:a).Every MPI rank launches a kernel of up to MAX_NUM_THREADS. This example definesMAX_NUM_THREADS as 16.b).Launch alltoall_kernel using kernel_launch.doca_dpa_kernel_launch();c).Using the doca_dpa_dev_put_signal_nb() function, copy the relevant sendbufto the correct recvbuf (according to the process' rank) for every OS process.Remember that multithreading is also used inside of the DPA threads.for (i = thread_rank; i < num_ranks; i += num_threads)doca_dpa_dev_put_signal_nb();d).Wait until the alltoall_kernel has finished.doca_dpa_event_wait_until();Note: Add an MPI barrier after waiting for the event to make sure that all of theprocesses have finished executing the alltoall_kernel.MPI_Barrier();After the alltoall_kernel is finished, the recvbuf of all the processes now contain the expected output of the all-to-all method.6.Destroy the a2a_resources:a).Free all the DOCA DPA memories.doca_dpa_mem_free();b).Unregister all the DOCA DPA host memories.doca_dpa_mem_unregister();c).Destroy all the DOCA DPA endpoints.doca_dpa_ep_destroy();d).Destroy the DOCA DPA worker.doca_dpa_worker_destroy();e).Destroy all the DOCA DPA events.doca_dpa_event_destroy();f).Destroy the DOCA DPA context.doca_dpa_destroy();g).Close the DOCA device.doca_dev_close();Chapter 6.Dependencies‣BlueField-3 or later‣Ubuntu 18.04/20.04/22.04 on the host (x86)‣Open MPI version 4.1.5rc2 or greater (included in DOCA installation)Chapter 7.Running the Application1.Refer to the following documents:‣NVIDIA DOCA Installation Guide for Linux for details on how to install BlueField-related software.‣NVIDIA DOCA Troubleshooting Guide for any issue you may encounter with the installation, compilation, or execution of DOCA applications.‣NVIDIA DOCA Applications Overview for additional compilation instructions and development tips of DOCA applications.2.The doca_dpa_all_to_all binary is located under /opt/mellanox/doca/ applications/dpa_all_to_all/bin/doca_dpa_all_to_all. To build all theapplications together, run:cd /opt/mellanox/doca/applications/meson buildninja -C build3.To build only the dpa_all_to_all application:a).Edit the following flags in /opt/mellanox/doca/applications/meson_options.txt:‣Set enable_all_applications to false‣Set enable_dpa_all_to_all to trueb).Run the commands in step 2.Note: doca_dpa_all_to_all is created under ./build/dpa_all_to_all/src/host/.Application usage:Usage: doca_dpa_all_to_all [DOCA Flags] [Program Flags]DOCA Flags:-h, --help Print a help synopsis-v, --version Print program version information-l, --log-level Set the log level for the program<CRITICAL=20, ERROR=30, WARNING=40, INFO=50, DEBUG=60>Program Flags:-m, --msgsize <Message size> The message size - the size of the sendbuf and recvbuf (in bytes).

Default is size of one integer times the number of processes.-d, --devices <IB device names> IB devices names that supports DPA,separated by comma without spaces (max of two devices). If not provided then a random IB device will be chosen.Running the Application4.Pre-run setup:‣Make sure that MPI is installed in your setup (openmpi is provided as part of thedoca-tools metapackage). Do not forget to update your LD_LIBRARY_PATH andPATH environment variable to include MPI. For example, if MPI is installed under / usr/mpi/gcc/openmpi-4.1.5rc2/ then run:export PATH=/usr/mpi/gcc/openmpi-4.1.5rc2/bin:$PATHexport LD_LIBRARY_PATH=/usr/mpi/gcc/openmpi-4.1.5rc2/lib:$LD_LIBRARY_PATH5.CLI example for running the application. Remember, this is an MPI program, so use mpirun to run the application (with the -np flag to specify the number of processes to run). The same command works for running the application on the host (x86) and the BlueField (Arm cores).‣The following runs the DPA all-to-all application with 8 processes using the default message size (the number of processes, which is 8, times the size of 1integer) with a random InfiniBand device:mpirun -np 8 /opt/mellanox/doca/applications/dpa_all_to_all/bin/doca_dpa_all_to_all‣The following runs DPA all-to-all application with 8 processes, with 128 bytes as the message size and with mlx5_0 and mlx5_1 as the IB devices:mpirun-np 8 /opt/mellanox/doca/applications/dpa_all_to_all/bin/doca_dpa_all_to_all -m 128 -d "mlx5_0,mlx5_1"Note: The application supports running with a maximum of 16 processes. If you tryto run with more processes, then an error is printed and the application exits.6.To run doca_all_to_all_dpa using a JSON file:doca_dpa_all_to_all --json [json_file]For example:cd /opt/mellanox/doca/applications/dpa_all_to_all/bin./doca_dpa_all_to_all --json ./dpa_all_to_all_params.jsonChapter 8.Arg Parser DOCA Flags Refer to NVIDIA DOCA Arg Parser Programming Guide for more information.Arg Parser DOCA FlagsChapter 9.References‣/opt/mellanox/doca/applications/all_to_all_dpa/src ‣/opt/mellanox/doca/applications/all_to_all_dpa/bin/ all_to_all_dpa_params.jsonNoticeThis document is provided for information purposes only and shall not be regarded as a warranty of a certain functionality, condition, or quality of a product.

URL Filter (6)Chapter 1.IntroductionDOCA applications are an educational resource provided as a guide on how to program on the NVIDIA® BlueField® DPU using DOCA API.For instructions regarding the development environment and installation, refer to the NVIDIA DOCA Developer Guide and the NVIDIA DOCA Installation Guide for Linux respectively.1.1. InstallationDOCA applications are installed under /opt/mellanox/doca/applications with each application having its own dedicated folder. Each application installs two directories:‣src – contains the source code and compilation files‣bin – contains pre-built binaries alongside runtime configuration filesThe application's binary is located under /opt/mellanox/doca/applications/<application_name>/bin/doca_<application_name>.1.2. CompilationAs applications are shipped alongside their sources, developers may want to modify someof the code during their development process and then recompile the applications. The files required for the compilation are the following:‣/opt/mellanox/doca/applications/meson.build – main compilation file for a project that contains all the applications‣/opt/mellanox/doca/applications/meson_options.txt – configuration file for the compilation process‣/opt/mellanox/doca/applications/<application_name>/src/meson.build –application-specific compilation definitionsTo recompile the application:1.Move to the application's directory:cd /opt/mellanox/doca/applications2.Prepare the compilation definitions:meson buildIntroduction pile the applications:ninja -C buildThe generated applications will be located under the ./build/ directory.1.3. Developer ConfigurationsWhen recompiling the applications, meson compiles them by default in "debug" mode. Therefore, the binaries would not be optimized for performance as they would include the debug symbol. For comparison, the application binaries shipped as part of DOCA's installation are compiled in "release" mode. To compile the applications in something other than debug, please consult Meson's configuration guide.The applications also offer developers the ability to use the DOCA Developer Log (DOCA_DLOG) on top of the existing DOCA Runtime Log (DOCA_LOG). Enabling the developer log during compilation activates various developer log messages that were left out of the release compilation. Activating the developer log may be done through enable_developer_log in the meson_options.txt file, or directly from the command line:1.Prepare the compilation definitions to use the developer log:meson build -Denable_developer_log=truepile the application(s):ninja -C buildChapter 2.Applications2.1. AllreduceThis application is a collective operation that allows data from many processing units to be collected and merged into a global result before being delivered to all processing units using an operator. The application is implemented using the UCX communication framework, which leverages the DPU's low-latency and high-bandwidth utilization of its network engine.2.2. Application RecognitionThis application identifies applications that are in use on a monitored networking node.The application is based on the deep packet inspection (DPI) library, which leverages DPU capabilities such as regular expression (RXP) acceleration engine, hardware-based connection tracking, and more.2.3.

DMA CopyThis application describes how to transfer files between the DPU and the host. The application is based on the direct memory access (DMA) library, which leverages hardware acceleration for data copy for both local and remote memory.2.5. DNS FilterThis application offloads DNS requests from the host to the DPU's Arm cores which allows reducing CPU overhead as they allow further DNS processing (e.g., allow/deny list) to bedone. The application is based on the DOCA Flow and RegEx libraries which leverage DPU capabilities such as regular expression (RXP) acceleration engine, building generic execution pipes in HW, and more.2.6. East-West Overlay EncryptionThis application, IPsec, sets up encrypted connections between different devices and works by encrypting IP packets and authenticating the packets' originator. It is based on a strongSwan solution which is an open-source IPsec-based VPN solution.2.7. File CompressionThis application shows how to compress and decompress data using hardware acceleration and to send and receive it. The application is based on the DOCA Compress and DOCA Comm-Channel libraries.2.8. File IntegrityThis application shows how to send and receive files in a secure way using the hardware Crypto engine. It is based on the DOCA SHA and DOCA Comm-Channel libraries.2.9. File ScanThis application describes how to scan a file using the hardware RegEx engine to find whether there are matches according to the compiled regular expressions. It is based on the DOCA RegEx library which leverages the DPU's regular expression (RXP) acceleration engine.2.10. FirewallThis application applies network security based on DOCA Flow gRPC and is used for remote programming of the DPU hardware. It leverages DPU capabilities such as building generic execution pipes in hardware, monitoring incoming and outgoing network traffic, and more.2.11.

L2 ReflectorThis application uses the data path accelerator (DPA) engine to intercept network traffic and swap the source and destination MAC addresses of each packet. It is based on the FlexIO API which leverages DPU capabilities such as high-speed DPA.2.13. L4 OVS FirewallThis application performs basic access control list (ACLs) operations. It allows the identification of different flows based on L3/L4 headers and executes different actions using Open vSwitch (OVS) commands.2.14. NATThis application, network address translation, switches packets with local IP addressesto global ones and vise versa. It is based on the DOCA Flow library which leverages DPU hardware capabilities such as building generic execution pipes in the hardware, executing specific actions on the traffic, and more.2.15. Secure ChannelThis application is used to establish a secure, network-independent communication channel between the host and the DPU based on the DOCA Comm Channel library.2.16. Simple Forward VNFThis application is a forwarding application that takes VXLAN traffic from a single RX port and transmits it on a single TX port. It is based on the DOCA Flow library which leverages DPU capabilities such as building generic execution pipes in the hardware, and more.2.17. SwitchThis application is used to establish internal switching between representor ports on the DPU. It is based on the the DOCA Flow library which leverages DPU capabilities such as building generic execution pipes in the hardware, and more.2.18.

DPA d vice MMA-A 数字音频接口用户手册说明书
User’s ManualThe d:vice™ MMA-A Digital Audio Interface is a high-quality dual-channel microphone preamplifier and A/D converter. It allows you to capture crystal-clear audio via your favorite recording / broadcasting apps. The d:vice™ can be used with most DPA microphones.C a b l e l e n g t h : 30 c m (11.8 i n )Two cables are supplied with the d:vice™ MMA-A: One Micro USB-B to iOS (Lightning)and one Micro USB-B to PC / Mac (USB-A).C a b l e l e n g t h : 100 c m (39.4 i n )Getting startedConnect your DPA microphone(s) to the MicroDot input(s) on the d:vice™, denoted I and II. (If only one mic is connected to either input, the signal will be interpreted as MONO and automatically sent to both output I and II.)Download the d:vice™ AppDownload and install the d:vice™ App from the Apple App Store.Please note that the d:vice™ willwork with most 3rd-party apps andtherefore can be used in varioussituations including live broadcasts, aswell as audio and video recordings.The d:vice™ MMA-A can be used right out of the box but to take full advantage of it, please refer to these instructions to get started using the d:vice™ App.GAINUse the GAIN slider to adjust input levels. Slide to the right to increase amplification, to the left to decrease. Make sure to keep an eye on the level meters when you are adjusting gain. The meters should stay in the green and yellow areas. FILTERThe FILTER button (low cut / high pass) cuts out unwanted, low-end frequencies (rumble) that can decrease the intelligibility of your recorded audio. In most cases we suggest using the FILTER button and if, for example, you are recording outside near a road with traffic, this setting is essential.MONITORUse the MON button to send audio to your headphones so you can hear what you are recording. Please note that a headphone must be connected to the iOS device, otherwise the button will not activate and you’ll be prompted to connect a headset. If the headset includes a microphone it must be connected prior to connecting the d:vice™ via the Lightning connector. This is due to the iOS ‘last entry active’ nature of operation. (We recommend using a wireless headset when using an iPhone 7.)LOCKUse the LOCK button to block 3rd party apps from controlling gain. G ain settings can be controlled and saved on the d:vice™ for use in your favorite recording / broadcasting apps. The lock button also controls the setting of the low cut / high pass filter. Saved locked settings are automatically activated the next time you connect to the d:vice™.MONOIf only one microphone is connected to either input I or II, MONO is chosen automatically. The mic input will be routed to both left and right output. Only one GAIN slider and FILTER button will be available in this mode.STEREOUse STEREO when you need to capture sound sources in stereo. Both microphones are controlled with one GAIN slider. Example: Ambiance sounds can be recorded in stereo using two mics that have the same sensitivity.Important: When using STEREO you must use two mics that are optimized for stereo recording, for instance the specially-selected d:screet™ 4060 pair included in the d:vice™ Kit VIDMK-4060-S.Other available kits include: SMK4060, ST4006*, ST4011*, ST2006*, ST2011** Must be used with DPA MMP-G amplifiers for connection to MicroDot.DUALUse DUAL when the gain must be set individually for input I and II (for example, with two different microphone types or in situations where two people with different voice levels are to be recorded). The FILTER buttons are also individual in this situation.PRESETSPresets store your preferred settings for specific microphone(s) and make your set up easier. After choosing your settings, create the preset by pushing the numbered preset button of your choice for three seconds. The next time you plug in the same mics, push your preset button and you are ready to go – no adjustmentsnecessary.Microphone placement and usagePlease refer to the manual(s) for the specific microphone included within the package.For use with PC / MacConnect the d:vice™ MMA-A to the USB input on your PC / Mac. The d:vice™ will now work as a normal external soundcard and you can use your regular programs to record or broadcast the audiofrom the connected microphones.CleaningThe black surface of the d:vice™ is fairly scratch resistant, but is sensitive to detergents. Avoid using solvents (such as: gasoline, acetone, alcohol, turpentine, etc) for cleaning purposes. A damp clothwith warm water is recommended.Made foriPhone 7 Plus, iPhone 7, iPhone 6s, iPhone 6, iPhone 5, iPad Pro (12.9-inch), iPad Air, iPad Air 2, iPad mini 4, iPod touch (6th gen).Compatible with Mac / PC / iOS RequirementsiOS version: 10 or laterConnection / Power: Lightning & USB 2.0SpecificationsNoise floor-114 dBFS, A-weightedFrequency range20-22 kHz ±0.2 dB (Fs = 48 kHz)20-40 kHz ±0.2 dB (Fs = 96 kHz)T otal harmonic distortion (THD) THD < -100 dB, 0.001% @ 1 kHz @ -10 dBFs Dynamic rangeTyp. 114 dBFull Scale Output1 Vrms @ 0 dB GainSupported sample rates44.1, 48 (default), 88.2, 96 kHzSample rates can be set by 3rd-party app Resolution24 bitFilter (low cut / high pass)2.

DPA应用手册
蔡海宁林斌2009-3-31
一、管脚定义
二、操作指导
本设计验证所选用的器件是CYCLONEIII, 另外也可以应用到CYCLONE, CYCLONEII, ARRIA GX, ARRIAII GX, STRA TIX, STRA TIX II, STRA TIXII GX STRA TIXIII, STRATIXIV E/GX等ALTERA高低端的FPGA上。
此外ADC是选取的TI ADC5277，如果客户采用的
是其他类型的ADC，需要在S2P文件中修改DESKEW_PATTERN和FSYNC_PATTERN。
如上图所示，在用户做好USER LOGIC并且调用DPA参考设计生成完整工程后，要按照以下步骤操作
1、用户逻辑通过SDI接口，使两个5277都发出DESKEW PATTERN, 即10101010……
2、使enable信号有效
3、当用户逻辑检测到DESKEW_SUC_OUT0为高后，通过SDI接口使第一个5277发出
FSYNC PATTERN, 即“000000111111”
4、当用户逻辑检测到FSYNC_SUC_OUT0为高后，可以让第一个5277发用户数据，此时
PDATA0_W上就是经过串并转换后的12位并行数据。
5、DPA设计中，一旦完成第一个5277的时钟同步，即刻进入第二个5277的处理过程，此
时用户逻辑重复3、4步骤即可。
此设计现在只处理两个ADC，它的最大处理能力是5个（CYCLONE3的锁相环最多只有5个输出），如果用户需要调整的话，只需将controller.v 中的parameter NUMBER改为所需的数就可以了。
此外还需要修改顶层，添加相应的端口等。
三、DPA原理
DPA（DYNAMIC PHASE ADJUST）是动态相位调整的简写。
它的工作原理是利用锁相环的动态移相功能，产生16个（也可能是8个，视不同设计而定）不同相位的时钟，去采集高速串行数据（已知的训练序列），其中若干个连续相位采集的数据是正确的，然后采用中间相位的时钟作为工作时钟。
四、波形
1、锁相环相位调整
2、deskew_suc_out与fsync_suc_out
DPA需要1500个CYCLE来完成，如果ADC不能及时发送FSYNC PA TTERN的话，这个时间会延长。
3、LVDS串并转换波形。
