Architecture of a high speed Reed-Solomon decoder

The authors propose an architecture for an error correction circuit suitable for high-rate data decoding of the Reed-Solomon code. It features a multiple-error correction capability of 4 errors or 8 erasures. The operational steps for multiple-error decoding are reduced by a 4-stage pipeline and a superscalar processor of a Galois field. The experimental circuit's 16 Mbyte/s rate of data decoding is sufficient for compressed video signals of high-definition as well as those of standard-definition TVs. >
