What are hardware components of CRC?

CRC hardware is a small hardware pipeline unit that takes as input a sequence of bits from a message and produces a CRC without using division or iteration. It is simple to understand the hardware’s working It consists of a 16 bit shift register with XOR operator as given in the handouts 1st all the values (bits) of the register is set to 0 than we start loading the bits of the messages one by one we shift one bit left to the register and check it if it is a 0 than shift again one bit to the left when 1 is loaded in the register the XOR operation with predefined devisor is performed and when all the message bits a shifted left than the result is in the register which is the CRC
