Abstract
On-the-fly error correction is provided by using the remainder from division of the encoded codeword by its generator polynomial to look up error values and locations in a memory. Alternatively, the syndromes are so employed. The values in the memory are predetermined and preassociated with each remainder or syndrome set. Alternatively, syndrome S.sub.0 directly yields the error value.
