| Abstract: | Based on the conventional errors correcting Reed Solomon(RS) decoder, an pipelined errors and erasures correcting RS decoder was presented by a novel modified decomposed inversionless Berlekamp Massey(B M) algorithm and three stage pipeline architecture. The RS decoder was characterized by the followings: easy timing control, direct circuit implementation, errors and erasures correcting, high speed with a rate of 1?byte per clock cycle, Verilog HDL implementation suitable reused in other relative VLSI design. The design was for DVD applications, and satisfied the system performance requirement. |
