Abstract
The present invention includes a method and device useful for decoding a Reed-Solomon (N, K) encoded message of m-bit symbols and corresponding syndromes, where N<=2 −1 and N−K=2t. Systolic calculation cells are used, organized to minimize complexity and computation time. Aspects of the invention include designs for syndrome calculation, division of polynomials over a Galois field, applying Euclid's algorithm, partitioning calculation cell arrays to reduce storage requirements, complexity and computation time, and evaluating an error location and polynomial and an error evaluator polynomial.
