A high speed Reed-Solomon decoder

Abstract

The Reed Solomon Code (RS Code) has been widely employed in digital audio/video equipment such as CD, DAT, and professional video recorders owing to its excellent capability for correcting burst errors and relatively easy implementation. We proposed an architecture of an error correction circuit suitable for high-rate data decoding of the Reed-Solomon Code. The circuit has encoder and decoder functions by 2 symbol random error correction as well as 4 symbol erasure correction. And 23 MByte/s rate of data decoding is sufficient for compressed video signals of high-definition as well as those of stand-definitions TVs.
