CRC Parallel Computation Implementation on FPGA

CRC computing by software can hardly meet with the high speed digital system.Classic LFSR circuit and other algorithm that derived from software are generally adopting as hardware solutions.Based on classic LFSR circuit,present a byte-wise CRC algorithm and express CRC-16 and CRC-CCITT in VHDL as two examples.The method is proved faster and less resource used than the others by the result synthesized in XST.
