The communicating parties agrees upon the size of message, M (x) and the generator polynomial, G (x). If r is the order of G (x), r, bits are appended to the low order end of M (x). This makes the block size bits, the value of which is xrM (x). The block xrM (x) is divided by G (x) using modulo 2 division.

WebJan 12, 2010 · We present a fast cyclic redundancy check (CRC) algorithm that performs CRC computation for any length of message in parallel.
