Error evaluator for inversionless Berlekamp-Massey algorithm in Reed-Solomon decoders

摘要

An error correcting Reed-Solomon decoder includes an error locator polynomial generator that generates an error locator polynomial and a scratch polynomial based on an inversionless Berlekamp-Massey algorithm (iBMA). An error location finder communicates with the error locator polynomial generator and generates error locations. An error values finder communicates with the error locator polynomial generator and generates error values directly from the error locator polynomial and the scratch polynomial.
