摘要
针对因FPGA的高速收发器、光电模块的光电转换过程引入的随机延时抖动和一定的误码率造成的多通道失同步问题,利用FPGA对数据链路层专门设计了系统同步算法使得多个通道之间能够保持同步,并在数据错误或丢失时以最小的代价重新取得同步。
Because of synchronization loss problem caused by random delay jitter of FPGA high-speed trans- ceiver and photoelectric conversion process, and a certain bit error rate of multi-channel, the synchronization al- gorithm used in data link layer of FPGA is designed specifically to maintain multi-channel synchronization. The re-synchronization is achieved at the least cost when occurring data errors or missing.
