Abstract
An apparatus and a method for accelerating Cyclic Redundancy Check (CRC) calculations. The apparatus includes a CRC circuit and an accelerator for accelerating the computation of the CRC code so that the CRC code is outputted immediately after the last bit of the input data stream is inserted to the CRC machine, thereby reducing the time required to compute the CRC calculation. The apparatus accelerates the CRC calculation by eliminating the need to append zeros to the input data stream.
