Abstract
A method for computing Reed-Solomon error control checkbytes in reduced time and with reduced gate count. Two syndromes, s and s , are computed for a sequence of data elements, using a selected primitive a that satisfies a selected primitive polynomial relation p(&agr;)=0. Each of two checkbytes, c and c , is expressed as a linear combination of the syndromes s and s , where each coefficient of each linear combination is expressed as a single power of the primitive &agr;, which is stored at the checkbyte generator for multiple use. This approach reduces gate count and associated time delay in formation of the usual Reed-Solomon multiplier coefficients.
