| 摘 要： | 通过在读写Flash存储器的数据分别进行RS编码和解码从而减少了Flash存储器失效对数据的影响.由传统的RS解码器复杂计算使得解码速度较慢不能满足对Flash存储器读写要求,因此在传统流水线结构的RS解码中采用伯利坎普--梅西算法避免求逆过程,减少了硬件开销,提高了解码速率,最后用软硬件对设计进行了严格的验证并在AL...

| Abstract: | In order to strongthen the datas which is storaged in the Flash Memory,a Reed Solomon Code decoder is used in desigining a Flash Memory Controller.A pipeline structure of this decoder is improved with reformulated inversionless Berlekamp——Massey algorithm,avoid computing invervse elements in GF（2m）.At the end of the article,designed the schematic for each module of the system and verified this design by means to FPGA chip. |
