Abstract

A decoder for decoding block error correction codes is described. The decoder includes a first search circuit to find roots of an error location polynomial corresponding to an error location and a second search circuit to find roots of an error location polynomial corresponding to an error location. A multiplexer is fed by the first search circuit and the second search circuit to produce an error location from the error location polynomial.
