摘要
针对已有ZYNQ半实物验证平台存在移植性差的缺点,围绕Xilinx ZYNQ芯片,建立了一个通用性高的高速高可靠算法半实物验证平台。该平台主要包含可编程逻辑(PL),ARM处理系统(PS)、上位机,以及对应的接口模块。为实现数据传输稳定可靠,在PS和PL之间设计了适合高速通信的双向握手协议。针对单片机模式下TCP/IP长时间通信不稳定的问题,额外增设串口作为PS和上位机之间通信的控制接口。最后,基于该平台搭建了一个摄像头图像实时传输显示平台。实测结果表明,该验证平台工作稳定可靠,上行和下行数据传输速率分别达到144 Mbit/s和133 Mbit/s。
In view of the poor portability of the existing half-physical verification platform based on ZYNQ,a high-speed and reliable algorithm half-physical verification platform with high versatility is established based on Xilinx ZYNQ chip.The platform is mainly composed of the programmable logic(PL),ARM processing system(PS),the host computer,and the corresponding interface module.A two-way handshake protocol,which is suitable for high-speed communication between PS and PL,is proposed to achieve stable and reliable data transmission.In order to solve the problem of long-time communication instability of TCP/IP in MCU mode,a serial port is added as the control interface between PS and PC.Finally,a real-time camera image transmission and display platform is built based on this platform.The experimental results show that the data transmission of the verification platform is stable and reliable and the data transmission rates of uplink and downlink are up to 144 Mbit/s and 133 Mbit/s respectively.
