Design and Implementation of Reed-solomom Decoder Based on FPGA
【摘要】 采用改进型Berlekamp_Massey(RiBM)算法设计并实现了基于FPGA的符合DRM_DCP接口协议的RS(255,207)译码器,可实现对每个码字(255个码元)中不多于24个码元的错误进行纠正。此外,介绍了设计中所采用的一种层次化数字信号处理IP的设计流程,可有效的提高设计和验证的效率。
【Abstract】 This paper presents an implementation of RS(255,207) decoder for DRM_DCP protocol,which is designed based on the Modified Berlekamp_Massey algorithm.The proposed circuit is capable of correcting up to 24 errors in every frame.This design use a hierarchical design/verification flow for digital signal processing IP which can effectively prompt the design efficiency.
