SpecificationsThis section provides the detailed information about the electrical design and practical considerations that go into the EVK board. Figure 1 describes each block in the high-level block diagram of the EVK board.Figure 1. MCIMX8M-EVK block diagramFigure 2 shows the overview of the i.MX 8M EVK board.SpecificationsFigure 2. i.MX 8M EVK board overview2.1. ProcessorThe i.MX 8M processors represent NXP Semiconductor’s latest achievement in integrated multimedia-focused products offering high performance processing with a high degree of functional integration, targeted towards the growing market of connected devices. The i.MX 8M processor features NXP’s advanced implementation of the Quad Arm Cortex®-A53+ Arm Cortex-M4 core, which operates at speeds up to 1.5 GHz. i.MX 8M includes integrated power management module that reduces the complexity of external power supply and simplifies the power sequencing. Each processor provides a 32-bit LVDDR3L/DDR4/LPDDR4 memory interface and other interfaces for connecting peripherals, such as HDMI, LCD, WLAN, Bluetooth™, GPS and camera sensors.For more detailed information about the processor, please refer to the datasheet and reference manual on /i.MX8M.2.2. Boot mode operations and selectionsThe i.MX 8M Applications Processor can be the boot configuration selected on SW802 or by the boot configuration stored on internal eFUSE. Alternatively, the i.MX 8M can download a program image from a USB connection when configured in serial downloader mode. The method used to determine where the processor finds its boot information is from two dedicated BOOT MODE pins. Table 2 shows the values used in the two methods.Figure 3. Boot mode selection using SW802Table 2. Boot mode pin settingsBOOT_MODE1 BOOT_MODE 0 Boot source0 0 Boot from fuses0 1 Serial downloader1 0 Internal boot1 1 ReservedIt is important for the developer to remember that these two pins are tied to the BOOT modules, therefore, on i.MX 8M EVK board, use a dual-switch (SW802) to select the input voltage of these two pins, 0 or 3.3 V. If the developer wants to boot the program Image from the Fuses Mode, the position of the switch 1 and 2 must be set to OFF, it is the same principle to choose the Serial Downloader Module or Internal Boot Module to load bootable code into the processor.If the method of determining the bootable source code is selected to be from the hardware, then the developer must set the switch S802:MODE0 to OFF, MODE1 to ON, and the four i.MX 8M pins must be set on the EVK board as Table 3 and Figure 4.Table 3. Boot mode settingBOOT configuration SW801Boot from EMMC 0010Boot from SD2 1100SpecificationsFigure 4. Boot mode setting using SW801On the i.MX 8M EVK board, the default boot mode is from eMMC device. There is one SD connector on the board. The board will check the eMMC connector first and then the SD connector. If you put the boot card into SD connector, and set the boot configuration as “BOOT from SD2”, the board will boot from the SD by default.NOTEFor more information about the boot module, such as the meaning ofevery bit of the Boot Switch, please refer to i.MX 8M Reference Manualon /i.MX8M.2.3. Power treeThere is a +12 V external wall power supply that needs to be connected to the i.MX 8M EVK board at connector J902. The other powers from internal adapters, on the EVK board, use discrete device to power the system. Figure 5 shows the power tree.Figure 5. Power tree diagramIn Figure 5, the developer can get all the voltage supply rails used on the EVK board. When some modules are not working, the developer needs to test whether the voltage of this module is correct. Table 4 lists the power rails on the board.SpecificationsTable 4.

LPDDR4 DRAM memoryThe i.MX 8M EVK board has one 768 Meg × 32 (4 channels × 16 I/O) LPDDR4 SDRAM chip(MT53B768M32D4NQ-062 WT:B) for a total of 3 GB RAM memory.In the physical layout, the LPDDR4 chip is placed on the TOP side, the data traces are not necessarily connected to the LPDDR4 chips in sequential order, but for ease of routing, are connected as best determined by the layout and other critical traces.The DRAM_VREF can be created by a simple voltage divider using 1.5 K Ohm 1% resistors and 0.1 µF capacitors for stability. The relatively smaller-value resistors provide enough current to maintain a steady mid‐point voltage. The calibration resistors used by the LPDDR4 chips and processor are 240 Ohm 1% resistors.2.5. SD card slot (J1601)There is one MicroSD card connectors (J1601) on the i.MX 8M EVK board. J1601 on the i.MX 8M EVK board is the TF slot for SD2 interface. By default, this MicroSD connector supports one 4-bitSD3.0 card or MMC card.2.6. eMMC memory (U601)The eMMC interface is connected to uSDHC1 of i.MX 8M. It can support eMMC 5.0, eMMC and hinge type. MicroSD socket are co-layout, and the eMMC device is populated by default on the EVK board. To boot from eMMC, you need to change the Boot-mode switch (SW801) settings as shown in Table 3.2.7. Ethernet connector (J1201)There is one gigabit Ethernet module on the i.MX 8M processor. The developer can use the ENET connector to send/receive the ENET signals. The Ethernet subsystem of the i.MX 8M EVK board is provided by the Qualcomm AR8031 Ethernet Transceiver (U1201). The Ethernet Transceiver (or PHY) receives standard RGMII Ethernet signals from the MAC-NET core of the i.MX 8M Applications Processor. The processor takes care of all Ethernet protocols at the MAC layer and above. The PHY is only responsible for the Link Layer formatting. The PHY receives the clock signal from the ENET_TXC pin of i.MX 8M processor.2.8. USB connector (J901, J903)The i.MX 8M Applications Processors contain two USB 2.0/3.0 OTG controllers, with two integrated USB PHY. On the EVK board, one is used for USB host port and the other for the USB TYPE-C port.2.9. Audio input/output (J1101)The main Audio DAC used on the EVK board is CIRRUS LOGIC Low Power, high quality Stereo DAC, WM8524. The digital interface between i.MX 8M and WM8524 includes three signals:SYNC_CLK, BCLK, and DACDAT. The i.MX 8M also provides the MCLK to WM8960.i.MX 8M EVK includes one headphone interface (J1101). J1101 is a 3.5 mm 4-pole (or TRRS) phone jack.CAUTIONThe Stereo audio jack is designed to be connected with active speaker. Ifyou want to connect it with a headphone, please make sure that theheadphone has volume control functionality and set the headphone’svolume properly before wearing it. Please do not plug in the non-volume-control headphone directly. The audio output volume may be too loud fornon-volume-control headphone and may harm your hearing.Specifications2.10. UART connector (J1701)The i.MX 8M Applications Processor has four independent UART Ports (UART1 – UART4). Usually the developer can use a DB9 connector and a level shifter such as MAX3232 to complete the UART debug circuit. Nowadays, many computers may not have a RS-232 DB9 connector, so on the EVK board, SILICON LABS’s CP2105, there is a USB to Serial UART IC to convert the UART signal to the USB signal. Note that you need to make sure the CP2105 VCP Driver has been installed on your computer for proper operation. If not, you may download it from SILICON LABS’ website and install: https:///products/development-tools/software/usb-to-uart-bridge-vcp-driversOn the EVK board, UART1_TXD & UART1_RXD are used to output serial debugging information for A53-core. UART2_TXD & UART2_RXD are used to output serial debugging information for M4-core. No RTS or CTS signals are sent from the Processor to the Debug connector as these signals are ignored by most applications. The required terminal settings to receive debug information during the boot cycle are as shown in Table 5.Table 5. Terminal setting parametersData Rate 115,200 BaudData bits 8Parity NoneStop bits 12.11. JTAG connector (J401)The i.MX 8M Applications Processor accepts five JATG signals from an attached debugging device on dedicated pins. A sixth pin on the processor accepts a board HW configuration input, specific to the EVK board only. The five JTAG signals used by the processor are:•JTAG_TCK TAP Clock•JTAG_TMS TAP Machine State•JTAG_TDI TAP Data In•JTAG_TDO TAP Data Out•JTAG_nTRST TAP Reset Request (Active Low)2.12. Extension port (J1801)One Expansion port (J1801) is provided on the EVK board to generate audio card connector, and the developer can use the processor to perform audio features development.2.13. MIPI-CSI/MIPI-DSI connector (J1501, J1502, J1503)The i.MX 8M processor supports dual MIPI-CSI and single MIPI-DSI. The connectors are designed to support camera and LCD. The connectors are as shown in Figure 6.Figure 6. MIPI-DSI/CSI connectorNOTEThe dual MIPI-CSI connector on Rev B3 EVK board shares the same I2C bus, if you want to develop dual-camera applications using two identical camera modules (with the same I2C address), an SW patch may be required (e.g., power on camera0 while keep camera1 powered off, then change camera0 I2C address and power on camera1). Alternatively, you can use two camera modules with different I2C address. Rev B4 EVK improving by assigning a different I2C bus to each MIPI-CSI connector, therefore not requiring a SW patch.Specifications2.14. User interface buttonsThere are two user interface buttons on the EVK board.2.14.1. Power button (SW1701)The chip supports the use of a button input signal to request main SoC power state changes (i.e. ON or OFF) from the PMU.ON/OFF can be configured as debounce, OFF-to-ON time, and max timeout. The debounce and OFF-to-ON time can be configured as 0, 50, 100 and 500 ms. Debounce is used to generate the power-off interrupt. In the ON state, if ON/OFF button is held longer than the debounce time, the power-off interrupt is generated. OFF-to-ON time supports the time it takes to request power-on after a button has been held longer than the configured time. In the OFF state, if ON/OFF button is held longer than the OFF-to-ON time, the state will transit from OFF to ON. Max timeout can be configured as 5 s, 10 s, 15 s and disable. Max timeout can also be the time for requesting power down after ON/OFF button has been held for the defined time.2.14.2. Reset button (SW1702)In the ON state, holding the RESET button (SW1702) will force to reset the power rails except the VDD_SNVS on the i.MX 8M EVK board. The i.MX 8M applications processor will be immediately turned off and reinitiate a boot cycle from the OFF state.2.15. WiFi/BT (U1301/J1401)The MCIMX8M EVK board has two ways to support WiFi/BT function:1.Chip on board WiFi: LBEE5U91CQ-TEMP;2.M.2 WiFi/BT card.Both ways share the same UART interface for BT function, so the BT function cannot be used at the same time. For WiFi, there are two standalone PCIe interfaces for this purpose, and WiFi function can be used at the same time.2.16. User interface LED indicatorsThere are two LED indicators on the board. These LEDs have the following functions: •Main Power Supply (D1601)—Green – CPU is running on OD mode.—Red – WALL_12V_DC_JACK is provided and SW701 is powered on.—OFF – The board is powered off.•UART (D1702/D1703)—Green light flashing – The UART data transmitted to PC.—Orange light flashing – The UART data received from PC.2.17. HDMI connector (J1001)The i.MX 8M EVK board has a Type-A HDMI connector that can playback 4K video.EVK accessories3.

流光溢彩 飞利浦275M1RZ电竞显示器
流光溢彩飞利浦275M1RZ电竞显示器作者：***来源：《微型计算机》2020年第15期在如今的顯示器市场之中，电竞显示器作为一个细分领域，受到越来越多用户的关注。
同时，“四大金刚”（指采用IPS面板、144Hz以上刷新率、G-SYNC或FreeSync、2K分辨率的电竞显示器）也成了众多玩家选购的标准。
随着技术的进步，厂商也赋予了“四大金刚”们更多的功能和更好的性能，比如HDR、广色域等。
前不久飞利浦推出的275M1RZ电竞显示器就是这样一款产品，它除了具备“四大金刚”的素质，还支持HDR，并且采用了第二代Nano IPS面板，同时加入了“流光溢彩技术”。
对于这款集众多功能于一身的飞利浦275M1RZ来说，它的综合表现如何？我们将对其一探究竟。
西装革履下的“侠客”我评测过的电竞显示器连我自己也记不清到底有多少款了，这些显示器都有一个共同特点，那就是外观设计上总会有带着电竞游戏风格，从而展现它的电竞定位。
反观飞利浦275M1RZ，我认为它是一款最没有电竞风格的电竞显示器。
从外观上来看，它采用了与很多家用显示器相同的时尚设计，T字形的底座、银灰色配色、超窄边框......整体外观给我的感觉就像是一位身着西装革履的人。
如果不是看到它左下方的重点参数铭牌，你可能不会将它与电竞显示器联想到一起。
接口齐全，内置音效扬声器飞利浦275M1RZ电竞显示器的接口比较齐全，它配备了1个DisplayPort接口，两个HDMI2.0接口。
需要注意的是，用户在使用时我建议使用DisplayPort接口，因为只有DisplayPort才能达到2560×1440@165Hz，而如果是HDMI接口，最高只能上到2560×1440@144Hz。
此外，显示器还配备有一组3.5mm音频接口和4个USB3.2接口，其中两个接口还支持BC1.2快速充电功能。
我们知道，很多显示器都会内置有扬声器，但是音质都很一般，属于“听个响”级别。

Predator 掠夺者作为Acer 宏碁旗下的高端电竞系列，致力于为热爱电竞的用户提供高端电竞体验，为此，自掠夺者系列诞生以来，X34、X27等旗舰级显示器不断“自我革命”，克服技术难题，发布时下顶配。
新王者X38秉承掠夺者系列的苛刻要求，带着引领电竞行业标准的使命横空出世。
作为一款37.5英寸的曲面大屏显示器，X38能带来非常好的沉浸式游戏体验。
曲率高达2300R，这对于IPS 面板来说十分不易，分辨率为UWQHD+（3840*1600），配合21：9的窄边“带鱼屏”，游戏画面高清精致且宽广生动，这使得X38拥有了让玩家深度体验电竞游戏的基础。
疾速电竞不容延迟 内置G—Sync 锻造王者电竞赛场兵贵神速，除去网速手速，对于显示器来说，最大的变量就是硬件本身的刷新率和响应时间。
X38采用Acer 第二代革命级电竞面板，对响应时间进行大幅优化，速度快人一步，制霸游戏全服。
日常响应时间低至1ms，极限响应时间可达0.3ms，以肉眼难以分辨的速度做出及时响应，只要手速够快，没有爆不到的敌人。
同时，X38的最高刷新率支持175Hz，相比前一代“机皇”X27的144Hz，X38有资格担起新一代机皇之称。
无所畏惧的战场疾行，源于NVIDIA G-Sync 技术的加持。
Predotar 掠夺者全系采用G-Sync 硬件级芯片，利用主动同步原理，随时抓取并显示显卡渲染出的画面帧，实现更高的帧率，杜绝跳帧撕裂和卡顿。
搭配NVIDIA 显卡后，可以更好地将硬件技术优势转化为游戏中的胜势，比对手抢先一步获取战机，或许就可以掌握游戏战场地主动权。

硬解谁主沉浮,私人影院级享受的4K视频体验
目前主流的电脑显示器分辨率是1920x1080，也就是常说的FHD标准，不过在智能手机都开始朝2560x1440前进了，PC显示器显然还需要更进一步的强化，下一代的标准就是4K分辨率，也就是Utlra HD标准。
今年以来，戴尔、联想、华硕、三星等公司纷纷推出廉价型4K显示器，最便宜的只有4000多即可买到，预计今年底明年初就能降到3000元内，用户也更容易接受。
4K对我们来说不仅是一次分辨率升级，其影响远远比之前1680x1050分辨率升级到1920x1080还要大，从应用体验、UI优化及性能上都提出了更严峻的挑战，更重要的是4K即将来临之前，很多人对4K尚无清晰的认识。
从本文开始，超能网也会推出一系列有关4K分辨率的科普文章，从4K显示器到4K电视，从4K基础知识再到4K视频、游戏应用皆有涉及。
之前我们已经科普了下4K分辨率到底是什么，也看到了Windows 8.1系统对4K的优化支持，也见识到了4K游戏对显卡的夸张要求，不过今天看到的将是4K带给用户最为赏心悦目的享受。
相关文章推荐：4K系列之一：4K分辨率是什么4K系列之二：Windows 8.1下4K应用初体验4K系列之三：4K游戏要求有多高4K系列之四：4K显示器与电视机的选择4K视频编码：H.264、H.265、VP9谁主沉浮视频编码、解码以及视频格式的内容可谓浩如烟海，随便拿出一部分内容都可以写一本厚厚的书，今天我们也不可能一一给各个视频编码做传，简单来说说主要的视频编码的故事吧。
江湖上流传的视频编码变准不下数十种，每种标准都可以说是厂商与各利益组织竞争、妥协、合作后的产物，这里我们简单把它们划为两个阶段，第一阶段可称为1080p及之前的阶段，有三种标准胜出，第二个阶段可称为后1080p时代，也包括目前愈演愈烈的4K时代，不过这个阶段的编码标准还没有最后的胜利者，H.265及VP9还在博弈中。
高清编码标准第一阶段：MPEG-2、H.264、VC-1胜出跟电信联盟最终确立了WCDMA、CDMA2000、TD-SCDMA 三大3G标准一样，早前胜出的视频编码标准也有三种——MPEG-2、H.264及VC-1，其中MPEG-2问世比较早，也是最早实现硬解的，VC-1也叫MPEG-4 AVC，有两个名字是因为早前它是由两个组织命名的，国际电联ITUT-T、ISO/IEC国际标准化组织分别给它取了名字。
