Abstract
A memory system, Reed Solomon ('RS') Decoder, and method for decoding Reed-Solomon codewords includes: a Syndrome Computation engine configured as a first stage of a pipeline for receiving the RS codeword and computing one or more Syndromes; an initialization unit for providing initialization values for a key equation solver engine that generates the errata locator polynomial and the errata magnitude polynomial configured as a second stage; and as a third stage a Chien Search engine for receiving the error locator polynomial and determining the one or more locations of the one or more erasures and random errors in the received RS codeword and an error-value evaluation ('EE') engine for receiving the errata magnitude polynomial and determining the one or more magnitudes of the one or more erasures and random errors in the RS received codeword.
