A High-Speed Pipelined Design for CRC-8 ATM-HEC Circuit and a Comparative Study with Its Parallel and Serial Counterparts

The Cyclic Redundancy Check (CRC) can be termed as a “Sophisticated check sum”. The Linear Feedback Shift Registers (LFSRs) play a key role in the calculation of the CRC. A simple circuit based on LFSR performs the CRC calculation by means of managing one bit at time. The CRC circuit design can be proposed by implementation of serial design or parallel or pipelining. This paper puts forth the comparison results of all the three design possibilities of CRC-8 ATM HEC.
