Abstract: Cyclic Redundancy Check (CRC) algorithm is widely used in measurement & control and communication fields to improve the reliability for data transmission. However, traditional CRし algo- rithm based on the bit cannot meet the requirements of high-speed signal processing. By the look-up- table architecture and distributed operation in FPGA, the bottle-neck of speed can be resolved on a large scale. The CRC distributed algorithm was deduced, from which CRし distributed algorithm cor?responding to polynomials of any order and any bit width processing can be derived. The algorithm achieves a higner processing speed and better stability in actual applications.
