(26)180960SB1.0THE i960® PROCESSORThe 80960SB is a member of the 32-bit architecturefrom Intel known as the i960 processor family. Thesemicroprocessors were especially designed to servethe needs of embedded applications. The embeddedmarket includes applications as diverse as industrialautomation, avionics, image processing, graphicsand networking. These types of applications requirehigh integration, low power consumption, quickinterrupt response times and high performance.Since time to market is critical, embedded micropro-cessors need to be easy to use in both hardware and software designs.All members of the i960 processor family share a common core architecture which utilizes RISC technology so that, except for special functions, the family members are object-code compatible. Each new processor in the family adds its own special set of functions to the core to satisfy the needs of a specific application or range of applications in theembedded market.Figure 2. 80960SB Programming EnvironmentSIXTEEN 32-BIT GLOBAL REGISTERS SIXTEEN 32-BIT LOCAL REGISTERS g0g15r0r15 FOUR 80-BIT CONTROL REGISTERSFLOATING POINT REGISTERS ARCHITECTURALLYDEFINEDDATA STRUCTURESFFFF FFFFHINSTRUCTIONSTREAMINSTRUCTIONEXECUTIONPROCESSOR STATEREGISTERSINSTRUCTION POINTERARITHMETIC CONTROLSPROCESS CONTROLSTRACE CONTROLS ADDRESS SPACELOAD STORE0000 0000H INSTRUCTIONCACHE FETCH280960SB1.1Key Performance FeaturesThe 80960SB architecture is based on the mostrecent advances in microprocessor technology andis grounded in Intel’s long experience in the designand manufacture of embedded microprocessors.Many features contribute to the 80960SB’s excep-tional performance:rge Register Set. Having a large number ofregisters reduces the number of times that aprocessor needs to access memory. Moderncompilers can take advantage of this feature tooptimize execution speed. For maximum flexi-bility, the 80960SB provides thirty-two 32-bitregisters and four 80-bit floating point registers.(See Figure 2.)2.Fast Instruction Execution. Simple functionsmake up the bulk of instructions in mostprograms so that execution speed can beimproved by ensuring that these core instruc-tions are executed as quickly as possible. Themost frequently executed instructions — suchas register-register moves, add/subtract,logical operations and shifts — execute in oneto two cycles. (Table 1 contains a list of instruc-tions.)3.Load/Store Architecture. One way to improveexecution speed is to reduce the number oftimes that the processor must access memoryto perform an operation. As with otherprocessors based on RISC technology, the80960SB has a Load/Store architecture. Assuch, only the LOAD and STORE instructionsreference memory; all other instructionsoperate on registers. This type of architecturesimplifies instruction decoding and is used incombination with other techniques to increaseparallelism.4.Simple Instruction Formats. All instructionsin the 80960SB are 32 bits long and must bealigned on word boundaries. This alignmentmakes it possible to eliminate the instructionalignment stage in the pipeline. T o simplify theinstruction decoder, there are only fiveinstruction formats; each instruction uses onlyone format. (See Figure 3.)5.Overlapped Instruction Execution. Load operations allow execution of subsequent instructions to continue before the data has been returned from memory, so that these instructions can overlap the load. The 80960SB manages this process transparently to software through the use of a register score-board. Conditional instructions also make use of a scoreboard so that subsequent unrelated instructions may be executed while the condi-tional instruction is pending.6.Integer Execution Optimization. When the result of an arithmetic execution is used as an operand in a subsequent calculation, the value is sent immediately to its destination register.At the same time, the value is put on a bypass path to the ALU, thereby saving the time that otherwise would be required to retrieve the value for the next operation.7.Bandwidth Optimizations. The 80960SB gets optimal use of its memory bus bandwidth because the bus is tuned for use with the on-chip instruction cache: instruction cache line size matches the maximum burst size for instruction fetches. The 80960SB automatically fetches four words in a burst and stores them directly in the cache. Due to the size of the cache and the fact that it is continually filled in anticipation of needed instructions in the program flow, the 80960SB is relatively insen-sitive to memory wait states. The benefit is that the 80960SB delivers outstanding performance even with a low cost memory system.8.Cache Bypass. If a cache miss occurs, the processor fetches the needed instruction then sends it on to the instruction decoder at the same time it updates the cache. Thus, no extra time is spent to load and read the cache.380960SBTable 1. 80960SB Instruction Set Data MovementArithmetic Logical Bit and Bit Field LoadStoreMoveLoad Address Add Subtract Multiply DivideRemainderModuloShiftExtended MultiplyExtended Divide And Not And And Not Or Exclusive Or Not Or Or Not Nor Exclusive NorNotNandRotateSet Bit Clear Bit Not Bit Check Bit Alter Bit Scan For Bit Scan Over Bit Extract ModifyComparisonBranch Call/Return Fault CompareConditional CompareCompare and IncrementCompare and DecrementUnconditional Branch Conditional Branch Compare and Branch Call Call Extended Call System Return Branch and Link Conditional Fault Synchronize Faults DebugMiscellaneous Decimal Floating Point Modify Trace ControlsMarkForce Mark Atomic Add Atomic Modify Flush Local RegistersModify ArithmeticControlsScan Byte for EqualTest Condition Code Move Add with Carry Subtract with Carry Move Real Scale Round Square Root Sine Cosine TangentArctangentLogLog BinaryLog NaturalExponentClassifyCopy Real ExtendedCompareSynchronousConversion Synchronous LoadSynchronous Move Convert Real to Integer Convert Integer to Real480960SB Figure 3.

Memory Addressing Modes•12-Bit Offset •32-Bit Offset •Register-Indirect •Register + 12-Bit Offset •Register + 32-Bit Offset •Register + (Index-Register x Scale-Factor)•Register x Scale Factor + 32-Bit Displacement •Register + (Index-Register x Scale-Factor) +32-Bit Displacement Scale-Factor is 1, 2, 4, 8 or 161.1.2Data TypesThe 80960SB recognizes the following data types:Numeric:•8-, 16-, 32- and 64-bit ordinals •8-, 16-, 32- and 64-bit integers •32-, 64- and 80-bit real numbers Non-Numeric:•Bit •Bit Field •T riple Word (96 bits)•Quad-Word (128 bits)1.1.3Large Register Set The 80960SB programming environment includes a large number of registers. In fact, 32 registers are available at any time. The availability of this many registers greatly reduces the number of memory accesses required to perform algorithms, which leads to greater instruction processing speed.There are two types of general-purpose register:local and global. The global registers consist ofsixteen 32-bit registers (g0 though g15) and four580960SB 80-bit registers (fp0 through fp3). These registersperform the same function as the general-purposeregisters provided in other popular microprocessors.The term global refers to the fact that these registersretain their contents across procedure calls.The local registers, on the other hand, are procedurespecific. For each procedure call, the 80960SBallocates 16 local registers (r0 through r15). Eachlocal register is 32 bits wide. Any register can also beused for single or double-precision floating-pointoperations; the 80-bit floating-point registers areprovided for extended precision.1.1.4Multiple Register SetsTo further increase the efficiency of the register set,multiple sets of local registers are stored on-chip(See Figure 4). This cache holds up to four localregister frames, which means that up to threeprocedure calls can be made without having toaccess the procedure stack resident in memory.Although programs may have procedure calls nestedmany calls deep, a program typically oscillates backand forth between only two to three levels. As aresult, with four stack frames in the cache, the proba-bility of having a free frame available on the cachewhen a call is made is very high. In fact, runs ofrepresentative C-language programs show that 80%of the calls are handled without needing to accessmemory.If four or more procedures are active and a newprocedure is called, the 80960SB moves the oldestlocal register set in the stack-frame cache to aprocedure stack in memory to make room for a newset of registers. Global register g15 is the framepointer (FP) to the procedure stack.Global and floating point registers are not exchangedon a procedure call, but retain their contents, makingthem available to all procedures for fast parameterpassing.1.1.5Instruction CacheTo further reduce memory accesses, the 80960SBincludes a 512-byte on-chip instruction cache. Theinstruction cache is based on the concept of localityof reference; most programs are not usuallyexecuted in a steady stream but consist of manybranches, loops and procedure calls that lead to jumping back and forth in the same small section of code. Thus, by maintaining a block of instructions in cache, the number of memory references required to read instructions into the processor is greatly reduced.T o load the instruction cache, instructions are fetched in 16-byte blocks; up to four instructions can be fetched at one time. An efficient prefetch algorithm increases the probability that an instruction will already be in the cache when it is needed.Code for small loops often fits entirely within the cache, leading to a great increase in processing speed since further memory references might not be necessary until the program exits the loop. Similarly,when calling short procedures, the code for the calling procedure is likely to remain in the cache so it will be there on the procedure’s return.1.1.6Register Scoreboarding The instruction decoder is optimized in several ways.One optimization method is the ability to overlap instructions by using register scoreboarding.Register scoreboarding occurs when a LOAD moves a variable from memory into a register. When the instruction initiates, a scoreboard bit on the target register is set. Once the register is loaded, the bit is reset. In between, any reference to the register contents is accompanied by a test of the scoreboard bit to ensure that the load has completed before processing continues. Since the processor does not need to wait for the LOAD to complete, it can execute additional instructions placed between the LOAD and the instruction that uses the register contents, as shown in the following example:ld data_2, r4ld data_2, r5Unrelated instruction Unrelated instruction add r4, r5, r6In essence, the two unrelated instructions between LOAD and ADD are executed “for free” (i.e., take no apparent time to execute) because they are executed while the register is being loaded. Up to three load instructions can be pending at one time with three corresponding scoreboard bits set. By exploiting this feature, system programmers and compiler writers have a useful tool for optimizing execution speed.680960SB Figure 4. Multiple Register Sets Are Stored On-Chipr 15r 0310ONE OF FOUR LOCAL REGISTER SETS REGISTER CACHE LOCAL REGISTER SET1.1.7Floating-Point Arithmetic In the 80960SB, floating-point arithmetic has been made an integral part of the architecture. Having the floating-point unit integrated on chip provides two advantages. First, it improves the performance of the chip for floating-point applications, since no additional bus overhead is associated with floating-point calculations, thereby leaving more time for other bus operations such as I/O. Second, the cost of using floating-point operations is reduced because a separate coprocessor chip is not required.The 80960SB floating-point (real-number) data types include single-precision (32-bit), double-precision (64-bit) and extended precision (80-bit) floating-point numbers. Any registers may be used to executefloating-point operations.The processor provides hardware support for bothmandatory and recommended portions of IEEEStandard 754 for floating-point arithmetic, includingall arithmetic, exponential, logarithmic and othertranscendental functions.T able 3 shows executiontimes for some representative instructions.1.1.8 High Bandwidth Bus The 80960SB CPU resides on a high-bandwidthaddress/data bus. The bus provides a direct commu-nication path between the processor and the memory and I/O subsystem interfaces. The processor uses the bus to fetch instructions,manipulate memory and respond to interrupts. Bus features include:•16-bit data path multiplexed onto the lower bits of the 32-bit address path •Eight 16-bit half-word burst capability which allows transfers from 1 to 16 bytes at a time •High bandwidth reads and writes with25.6MBytes/s burst (at 16 MHz)Table 4 defines bus signal names and functions;Table 5 defines other component-support signalssuch as interrupt lines.Table 3.

Two of the interrupt pins can be configured to provide 8259A-style handshaking for expansion beyond four interrupt lines.1.1.10Debug FeaturesThe 80960SB has built-in debug capabilities. There are two types of breakpoints and six trace modes.Debug features are controlled by two internal 32-bit registers, the Process-Controls Word and the T race-Controls Word. By setting bits in these control words,a software debug monitor can closely control how the processor responds during program execution.The 80960SB provides two hardware breakpoint registers on-chip which, by using a special command, can be set to any value. When the instruction pointer matches either breakpoint register value, the breakpoint handling routine is automati-cally called.The 80960SB also provides software breakpoints through the use of two instructions: MARK and FMARK. These can be placed at any point in a program and cause the processor to halt execution at that point and call the breakpoint handling routine.The breakpoint mechanism is easy to use and provides a powerful debugging tool.Tracing is available for instructions (single step execution), calls and returns and branching. Each trace type may be enabled separately by a special debug instruction. In each case, the 80960SB executes the instruction first and then calls a trace handling routine (usually part of a software debug monitor). Further program execution is halted until the routine completes, at which time execution resumes at the next instruction. The 80960SB’s tracing mechanisms, implemented completely in hardware, greatly simplify the task of software test and debug.1.1.11Fault DetectionThe 80960SB has an automatic mechanism to handle faults. Fault types include floating point,trace and arithmetic faults. When the processor detects a fault, it automatically calls the appropriate fault handling routine and saves the current instruction pointer and necessary state information to make efficient recovery possible. Like interrupt handling routines, fault handling routines are usually written to meet the needs of specific applications and are often included as part of the operating system or kernel.For each of the fault types, there are numerous subtypes that provide specific information about a fault. For example, a floating point fault may have the subtype set to an Overflow or Zero-Divide fault.The fault handler can use this specific information to respond correctly to the fault.1.1.12Built-in TestabilityUpon reset, the 80960SB automatically conducts an exhaustive internal test of its major blocks of logic.Then, before executing its first instruction, it does a zero check sum on the first eight words in memory to ensure that the memory image was programmed correctly. If a problem is discovered at any point during the self-test, the 80960SB asserts its and will not begin program execution. Self test takes approximately 47,000 cycles to complete.System manufacturers can use the 80960SB’s self-test feature during incoming parts inspection. No special diagnostic programs need to be written. The test is both thorough and fast. The self-test capability helps ensure that defective parts are discovered before systems are shipped and, once in the field,the self-test makes it easier to distinguish between problems caused by processor failure and problems resulting from other causes.1.1.13CHMOSThe 80960SB is fabricated using Intel’s CHMOS IV (Complementary High Speed Metal Oxide Semicon-ductor) process. The 80960SB is available at 10MHz in the QFP package and at 10and 16 MHz in the PLCC package.880960SBTable 4. 80960SB Pin Description: Bus Signals (Sheet 1 of 2)NAME TYPE DESCRIPTIONCLK2I SYSTEM CLOCK provides the fundamental timing for 80960SB systems. It is divided by two inside the 80960SB to generate the internal processor clock.A31:16O T.S.ADDRESS BUS carries the upper 16 bits of the 32-bit physical address to memory. It is valid throughout the burst cycle; no latch is required.AD15:1, D0I/O T.S.ADDRESS/DATA BUS carries the low order 32-bit addresses and 16-bit data to and from memory. AD15:4 must be latched since the cycle following the address cycle carries data on the bus.A3:1O T.S.ADDRESS BUS carries the word addresses of the 32-bit address to memory. These three bits are incremented during a burst access indicating the next word address of the burst access. Note that A3:1 are duplicated with AD3:1 during the address cycle.ALEO T.S.ADDRESS LATCH ENABLE indicates the transfer of a physical address.ALE is asserted during a T a cycle and deasserted before the beginning of the T d state. It is active HIGH and floats to a high impedance state during a hold cycle (T h ).AS O T.S.ADDRESS STATUS indicates an address state.AS is asserted every T a state and deasserted during the following T d state.AS is driven HIGH during reset.W/R O T.S.WRITE/READ specifies, during a T a cycle, whether the operation is a write or read. It is latched on-chip and remains valid during T d cycles.DENO T.S.DATA ENABLE is asserted during T d cycles and indicates transfer of data on the AD lines. The AD lines should not be driven by an external source unless DEN is asserted. When DEN is asserted, outputs from the previous cycle are guaranteed to be three-stated. In addition,DEN deasserted indicates inputs have been captured; therefore input hold times can be disregarded.DEN is driven HIGH during reset.DT/RO T.S.DATA TRANSMIT / RECEIVE indicates the direction of data transfer to and from the bus. It is low during T a and T d cycles for a read or interrupt acknowledgment; it is high during T a and T d cycles for a write. DT/R never changes state when DEN is asserted. DT/R is driven HIGH during reset.READY IREADY indicates that data on AD lines can be sampled or removed. If READY is not asserted during a T d cycle, the T d cycle is extended to the next cycle by inserting a wait state (T w ).I/O = Input/Output, O = Output, I = Input, O.D. = Open Drain, T.S. = Three-state。

星际音频JIB CT电缆测试器用户指南说明书
Table of Contents (1)Operation (2) (2)Connections (2)Select Test (2)Indications (3)Advanced Tests (3)Other Special Cables (4)Custom Cables (5)Warranty (7)Registration Card ...........................Back CoverIntroduction Battery InstallationIntroductionThank you for purchasing the Galaxy Audio JIB/CT Cable Tester. The CT is designed to test a wide variety of commonly used audio cables and quickly answer the question, “Is this cable good or bad?”A unique computer controlled circuit tests the cable 200 times per second, which allows the CT to detect and display intermittent problems that other cable testers fail to catch.The CT control panel simply consists of a rotary switch, one Green LED, and one Red LED. A quick reference chart is located on the bottom of the unit.TOP BOTTOMConnectors and Controls1Operation1. Battery Installation: Switch to OFF position. Remove the Battery Drawer and install a 9-volt alkaline battery, being careful to not pinch any of the wires when reinstalling the Drawer. Due to the low power consumption design and the Auto Shutoff feature, the battery life of a standard 9V alkaline should be over 100 hours. The Auto Shutoff feature switches off the CT after approximately 5 minutesof inactivity. To reset the CT after Auto Shutoff, simply rotate the switch to the “Off” position and then back to your previous setting. If the Red LED becomes too dim to see, replace the battery with a fresh 9V alkaline.2. Connections: Plug one end of the cable to be tested into the appropriate connector on the “A” side of the CT, and the other end of the cable into the “B” side. All of the connectors on the “A” side are duplicated on the “B” side except for the XLR jacks, where the “A” side has a Female XLR and the “B” side has a Male XLR. CAUTION: Do not connect the CT to any audio device or system. Damage may result to the CT and/or the audio device.3. Select Test: Rotate the switch to select the number of conductors within the cable.NOTE: For accurate results it is necessary to select the correct number of conductors within the cable under test. If in doubt, you may want to remove one of the connector covers to count the conductors emerging from the cable.The following chart lists the number of conductors found in commonly used audio cables. When speaking of 1/4” or 1/8” connectors, the terminology TRS (Tip, Ring, Sleeve) is used to describe the conductors as they appear on the plugs. A Mono cable (2 conductor) would use only the Tip and Sleeve (TS), while a Stereo or balanced cable (3 conductor) would use all three Tip, Ring, and Sleeve (TRS).24. Indications: As the Selector Switch is rotated from the OFF position, the Green LED will blink twice to indicate the CT is ready to test. The Red LED will then light momentarily to indicate the cable is being tested. If the cable fails the test, the Red LED will remain lit. If the cable passes the test, the Red LED will go out and the Green LED will light. At this point you may want to check for intermittent problems by flexing or wiggling the cable. Be aware that cables can become intermittent because of wiring problems or failure of the connector contacts. Any change in the LED indications, even if only momentary, means that the cable has an intermittent problem and cannot be relied upon.5. Advanced Tests: Most of the standard audio cables will test either Pass or Fail according to the indications described above. However, there are some alternative indications given for Pass and Fail for certain cables. The chart below describes some of these cables and what indications to expect.36. Other Special Cables: Male-to-Male or Female-to-Female XLR Cables: Use a known good adapter cable to “change the gender” of one of the cable ends by connecting it in series with the cable under test. Female TS or TRS connectors: Use a known good Male-to-Male cable to “change the gender” to Male by connecting it in series with the cable under test.47. Custom Cables. The CT is designed to test industry standard and commercially available cables and adapters. The CT may not give accurate results for cables wired otherwise.NOTES56ONE YEAR LIMITED WARRANTYThis warranty gives you specific legal rights, and you may also have other rights which may vary from state to state.

The CAT803, CAT809, and CAT8 0 are direct replacements for the MAX803, MAX809 and MAX8 0 in applications operating over the industrial temperature range.These devices generate a reset signal, which is asserted while the power supply voltage is below a preset threshold level and for at least 40 ms after the power supply level has risen above that level. The underlying floating gate technology, AE 2(TM) used by Catalyst Semiconductor, makes it possible to offer any custom reset threshold value. Seven industry standard threshold levels are offered to support +5.0V, +3.3V, +3.0V and +2.5V systems.The CAT803 has an open-drain RESET output (active LOW). The CAT803 requires a pull-up resistor on the reset output.The CAT809 features a push-pull RESET output (active LOW) and the CAT8 0 features a push-pull RESET output (active HIGH).Fast transients on the power supply are ignored and the output is guaranteed to be in the correct state at V cc levels as low as .0V.The CAT803, CAT809, and CAT8 0 are available in both the compact 3-pin SOT-23 and SC-70 packages.PIn COnfIGuRATIOn(CAT803)CAT809(CAT810)GNDRESET (RESET)V CC3-Lead SOT-233-Lead SC-70123THRESHOLD SuffIX SELECTORnominal Threshold Voltage Threshold SuffixDesignation4.63V L 4.38V M 4.00V J 3.08VT 2.93V S 2.63V R 2.32VZfor Ordering Information details, see page 11.CAT803, CAT809, CAT8102Doc.

An advantage of the open-drain output includes the ability to “wire AND” several outputs together to form an inexpensive logic circuit. It is also possible to have the pull-up resistor connected to a different supply which can be higher than the CAT803 V CC pin. The value of the pull-up resistor is not critical in most applications, typical values being between 5kΩ and 10kΩ.Power Supplyfigure 6.
