CRC is transmitted by the data block to be calculated, which is calculated by the block to be transmitted as a continuous bit composed of a bunch of a whole value and this value divided by a particular divisor, usually binary, said that this division is also known as derivative polynomial (Generation Polynomial), the divisor rests general hardware or software design provided by the manufacturers, while the number of inter-bit value as the CRC bits to yield a depending on the number.
