High Speed Interleaved Reed-Solomon Error Detection and Correction System

Due to the relatively high raw error rate on present day Optical Media, a high performance, real-time error detection and correction system was necessary to achieve the kind of data reliability required in computer storage systems. This paper describes such an error detection and correction system, based on an interleaved Reed-Solomon code, that is capable of correcting multiple burst errors. A pipelined architecture combines several special-purpose processors designed for specific decoding functions. This system, operating at speeds of up to 30 megabits per second, achieves an increase in reliability of more than ten orders of magnitude.
