Reed-Solomon code encoder and syndrome generator circuit

Image Number 7 for United States Patent #4777635.

Disclosed is a serial encoder and time domain syndrome generator circuit utilized in a Reed-Solomon code application where the code has been defined with the conventional or standard representation of a finite field. The encoder will process k bits of an m-bit symbol per clock cycle, where 1.ltoreq.k.ltoreq.m and k evenly divides m. The encoder will process data in an interleave mode wherein data symbols of multiple codewords are interleaved in an interleaved data block. The encoder allows pipeline processing of register data within the encoder and time domain syndrome generator circuit to minimize circuit delay, and a linear network within the encoder is reduced in complexity by selecting a self-reciprocal code generator polynomial.
