基于DVD应用的流水线RS-PC解码的VLSI设计

VLSI design of pipeline RS-PC decoder based on DVD applications

基于DVD数据纠错的应用,设计实现了全程流水线处理的RS-PC解码,采用分解的无逆BM(Berlekamp-Massey)算法和脉动时序控制实现RS解码器的三级流水线处理,采用行列独立的缓冲器和纠错解码器实现行列纠错的两级流水线处理。该RS-PC解码能达到非常快的处理速度,在行列纠错处理无迭代的情况下,数据率可达到每时钟一个字节。

In this paper,a high speed pipeline Reed-Solomon Product-Code(RS-PC)decoder for DVD applications is pre-sented.The RS decoder features an area-efficient key equation solver using a novel modified decomposed inversionless Berlekamp-Massey algorithm and pipelined by using systolic arrays in cycle controller.Three-stage pipeline is used in RS decoder.Using two frame-buffer controllers,a(182,172)row RS decoder and a(208,182)column RS decoder can pipelined.The proposed RS-PC decoder solution can operate at a rate of1byte per clock cycle.It is a very high speed VLSI Design of a Pipeline Reed-Solomon Product-Code(RS-PC)Decoder for high speed DVD applications.
