基于FPGA的高速串行链接通信设计与实现

摘要

为了满足某高速高精IC设备的步进扫描运动控制系统中高精度数据实时传输的要求,设计了一种使用光纤作为通信介质的高速串行链接通信解决方案,描述了该通信协议的物理层、传输层和应用层.最后运用Verilog HDL语言在FPGA上编程实现.该通信方案已经在运动控制卡和伺服控制板卡通信中得到应用,实践证明其具有可靠性高、传输数据准确、编程容易等优点.%In order to meet the requirement of high-precision real-time data transmission in the step-scan motion control system which was used in one high-speed and precise IC equipment,a high-speed spenal link communication solution was designed which used optical fiber as the communictaion medium.The physical layer, transport layer and application layer of the communication protocol were described.The paper used Verilog HDL language to program on the FPCA board.The scheme was used in the communiaUion between the motion control board and the power amplifier control board.A case was presented to show that the scheme has many advantages, such as high reliability, high-precision data transmission and facilitiy programming.
