Abstract
A method and circuitry for generating N-bit parallel CRC code from an N-bit parallel data input source. A generating polynomial function is used to express an array of exclusive-OR gates to which the N-bit parallel data inputs are applied. A plurality of N latches is provided and connected to the exclusive-OR gate array in a feedback fashion to provide the plurality of N-bit parallel CRC codes according to the polynomial function.
