RS(511,495) decoder for NAND flash controller,decoding steps: (1)syndrome (2)Berlekamp-Massey (3)chien (4)forney

欧氏距离算法计算错误位置多项式，是Berlekamp-Massey的替代算法。消耗的硬件资源比Berlekamp-Massey算法多，但是可以更节省运算时间。-Euclidean distance algorithm to calculate the error position polynomial, is an alternative Berlekamp-Massey algorithm. The consumption of hardware resources is more than
