Abstract:
A method for computing error control checkbytes for a sequence of data, the method comprising:receiving a sequence of N+1 eight-bit data elements that are to be processed for error control purposes, where N is a selected positive integer; computing a first error control syndrome s0 as a sum of the sequence of data elements; computing a second error control syndromes s1 as a sum of the sequence of data elements, each multiplied by a selected power of an eight-bit array &agr; that satisfies a selected primitive polynomial relation p(&agr;)=&agr;8+&agr;4+&agr;3+&agr;2+1=0; and computing first and second checkbytes, c0 and c1, for the sequence of data elements as first and second linear combinations c0=s0Â·&agr;230âŠ•s1Â·&agr;232, c1=s0Â·&agr;231âŠ•s1Â·&agr;232.
