基于RocketIO的多路相机数据传输系统的设计

The implementation of multiple camera data transmission by RocketIO

数字/模拟图像数据传输一直是测控设备数据通讯中的重点和难点。针对Xilinx的Virtex-ⅡPRO系列FPGA内嵌的RocketIO收发器模块,设计了用于测控设备多路图形数据的高速传输系统。该系统充分利用了FPGA中集成的RocketlO收发器模块,采用BREFCLK差分输入参考时钟,8B/10B编码,预加重处理等技术。实现了多路图像高速、实时、远距离传输。单通道传输速率可以达到3.125Gb/s。

In the communication system of observation and control instrument, the high speed data of digital/analog camera transmission is the emphases and the difficulty all the time . Aiming at the RocketlO transceiver module of Xilinx Virtex-Ⅱ PRO FPGA .This paper designs a high-peed transmission system used on data transmission system. This system uses RocketlO module in the chip fully, BREFCLK differential input reference clock, 8B/10B decoder and pre-emphasis technology. Implements one RocketlO transmission at 3.125bps and delivers the data with the characters such as high speed, far distance, and real time.
