Abstract
Disclosed is a configurable Reed-Solomon (RS) decoder that comprises a parallel multiply accumulator having a data input to receive at least one RS codeword, the parallel multiply accumulator being configured to generate a syndrome array from the RS codeword. The configurable RS decoder also includes a Galois field computation unit coupled to the parallel multiply accumulator, and an RS decoder controller coupled to the parallel multiply accumulator and the Galois field computation unit, wherein the RS decoder controller controls the operation of the parallel multiply accumulator and the Galois field computation unit. The RS decoder may be configured for different numbers of symbols in the RS codewords, parity symbols in the RS codewords, and modulation types employed in creating the RS codewords.
