Abstract
A data processing system includes a decoder circuit, syndrome calculation circuit and hash calculation circuit. The decoder circuit is operable to apply a decoding algorithm to a decoder input based on a first portion of a composite matrix to yield a codeword. The syndrome calculation circuit is operable to calculate a syndrome based on the codeword and on the first portion of the composite matrix. The hash calculation circuit is operable to calculate a hash based on a second portion of the composite matrix. The decoder circuit is also operable to correct the codeword on the hash when the syndrome indicates that the codeword based on the first portion of the composite matrix is correct but a second test indicates that the codeword is miscorrected.
