存储系统数据通道的On-The-Fly纠错

OnTheFly ERROR CORRECTION IN STORAGE DATA CHANNELS

对于高性能、高可靠性存储系统，其控制器须具备实时在线检纠错能力。为了便于硬件实现ＯＴＦ（Ｏｎ－Ｔｈｅ－Ｆｌｙ）检纠错，本文提出了ＲＳ（Ｒｅｅｄ－Ｓｏｌｏｍｎ）码译码的并行Ｂｅｒｌｅｋａｍｐ算法，并设计了实现算法的模块化纠错硬件单元和相应控制逻辑。根据不同应用场合对纠错能力的要求，可以对这些模块化纠错硬件单元进行灵活的组合。

For highperformance, highavailable storage systems, The ability of realtime online error check & correction is neccessory. To accomplish OnThe_Fly error correction, a parallel Berlekamp algorithm for ReedSolomn decoding is presented and modular hardware error correction units are designed in this paper. According to error correction requirements these units can be combined arbitrarily for varible applications.
