Computation of a cyclic redundancy check is derived from the mathematics of polynomial division, modulo two. In practice, it resembles long division of the binary message string, with a fixed number of zeroes appended, by the "generator polynomial" string except that exclusive or operations replace subtractions. Division of this type is efficiently realised in hardware by a modified shift register, and in software by a series of equivalent algorithms, starting with simple code close to t… WebCRC_Start() Initializes seed and polynomial registers with initial values. Computation of CRC starts on rising edge of input clock. CRC_Stop() Stops CRC computation. …

WebCRC process can easily be implemented as a dividing circuit consisting of exclusive OR gates and one bit shift registers. Implementation is as follows. 1. The input register contains N bit, equal to the length of the FCS. 2. There can be up to n exclusive OR gates. 3. The presence or absence of a gate corresponds to the presence of a term http://www.christiealwis.com/Books/ErrorControls/Chapter_3-Cyclic_Redundancy_Code_or_Frame_Check_Sequence.pdf
