基于RocketIO的高速串行协议设计与实现

Design and Implementation of High Speed Serial Transmission Protocol Based on RocketIO

采用Xilinx公司Virtex-II Pro系列FPGA内嵌得SERDES模块——RocketIO作为高速串行协议的物理层,利用其8B/10B的编解码和串化、解串功能,实现了两板间基于数据帧的简单高速串行传输,并在ISE环境中对整个协议进行了仿真,当系统频率为100MHz,串行速率在2Gbps时,在验证板上用chipscope抓取的数据表明能够实现两板间数据的高速无误串行传输。

RocketIO,the SERDES module,which is embedded in the Virtex-II Pro FPGA of Xilinx company,is used as the physical layer of simple high speed serial transmission protocol.Its function of 8B/10B,serialize and deserialize are introduced to implement high speed transmission between two boards based on data packets.Aslo,the protocol is simulated in ISE environment,when system clock is 100MHz, serial speed is 2Gbps,the results obtained by chipscope on the validate board indicate the transmission is right.
