Abstract
A multi-byte cyclic redundancy check (CRC) calculation circuit and a method of calculating a multi-byte CRC. In one embodiment, the circuit includes: (1) a plurality of modules each configured to receive remainder bits in first inputs thereof and different numbers of portions of an input message in second inputs thereof and compute candidate CRC bits based thereon, (2) a storage element configured to receive output bits from one of the plurality of modules and provide the output bits to the first inputs as the remainder bits and (3) a multiplexer coupled to first outputs of the plurality of modules and configured to select from among the candidate CRC bits to yield a CRC for the input message.
