说明： 该设计使用8个AXI视频直接存储器访问（AXI VDMA）引擎同时移动16个流（8个传输视频流和8个接收视频流），每个流以1920 x 1080像素格式以60赫兹刷新率移动，每个像素24个数据位。此设计还具有额外的视频等效AXI流量，该流量由为1080p视频模式配置的四个LogiCORE AXI流量发生器（ATG）核心生成。ATG核心根据其配置生成连续的AXI流量。在本设计中，ATG被配置成以1080p模式生成AXI4视频流量。这使得系统吞吐量需求达到DDR的80%左右带宽。每个AXI VDMA由LogiCORE IP测试模式生成器（AXI TPG）核心驱动。AXI VDMA配置为在自由运行模式下运行。每个AXI VDMA读取的数据被发送到能够将多个视频流多路复用或叠加到单个输出视频流的通用视频屏幕显示（AXI OSD）核心。AXI OSD核心的输出驱动板载高清媒体接口（HDMI技术）视频显示接口通过RGB到YCrCb颜色空间转换器核心和逻辑核心IP色度重采集器核心。LogiCore视频定时控制器（AXI VTC）生成所需的定时信号。(The design uses eight AXI video direct memory access (AXI VDMA) engines to simultaneously move 16 streams (eight transmit video streams and eight receive video streams), each in 1920 x 1080 pixel format at 60 Hz refresh rate, and 24 data bits per pixel. This design also has additional video equivalent AXI traffic generated from four LogiCORE AXI Traffic Generator(ATG) cores configured for 1080p video mode. The ATG core generates continuous AXI traffic based on its configuration. In this design, ATG is configured to generate AXI4 video traffic in 1080p mode. This pushes the system throughput requirement to approximately 80% of DDR
bandwidth. Each AXI VDMA is driven from a LogiCORE IP Test Pattern Generator (AXI TPG)core. AXI VDMA is configured to operate in free running mode. Data read by each AXI VDMA is sent to a common Video On-Screen Display (AXI OSD) core capable of multiplexing or overlaying multiple video streams to a single output video stream.)

说明： 配置GTH ip的例子工程，选用7 series 芯片的GTH 113quad的四个通道，在程序中每个链路利用自己的恢复时钟进行数据解码，所以四个通道可以各自独立运行；成功工作在2.54Gb/s的链路状态，长时间（>24小时）的测试，误码率一直为0.(The GTH ip example project is configured with four channels of the GTH 113quad of the 7 series chip. Each link in the program uses its own recovery clock for data decoding, so the four channels can operate independently; the successful operation is at 2.54Gb/ The link state of s, long time (>24 hours) test, the bit error rate has been 0.)

16位右移位寄存器
下面描述的是一个位宽为16位的右移位寄存器，实际具有环形移位的功能，是在右移位寄存器的基础上将最低位的输出端接到最高位的输入端构成的。其功能为当时钟上升沿到达时，输入信号的最低位移位到最高位，其余各位依次向右移动一位。(16-bit right shift register
The following description is a right shift register with a bit width of 16 bits. It actually has the function of circular shift. It is based on the right shift register, which connects the lowest bit output terminal to the highest bit input terminal. Its function is that when the rising edge of the clock arrives, the lowest displacement of the input signal reaches the highest position, and the rest of you move one bit to the right in turn.)
