Comparison of serial data-input CRC and parallel data-input CRC design for CRC-8 ATM HEC employing MLFSR

Cyclic Redundancy check (CRC) is primarily used in the physical layer of transmission protocols (viz., Ethernet and Bluetooth). CRC computation can be done in two ways; either serial computation or parallel computation. CRC computation implement linear feedback shift registers (LFSRs). The proposed paper gives an insight of serial and parallel implementation of CRC 8- CCITT widely used in Header Error Control in Asynchronous Transfer Mode (ATM HEC).
