摘要：A Reed-Solomon decoder and a decoding algorithm executed by the decoderare disclosed. The decoder includes a syndrome computer and a syndrome processor.The syndrome computer is a pipelined functional unit for computing syndromes from areceived codeword and storing erasure location members as flagged by an Erasure Flagsignal. The syndrome processor includes a pipelined functional unit and a Chien searchcircuit for receiving from said syndrome computer the computed syndromes, erasurelocations, and number of erasures and computing erasure locator polynomial, modifiedsyndrome polynomial, error locator and error evaluator polynomials, error-erasurelocator polynomial, and error value at an error location at each error location found bythe Chien search circuit.
