"WebFrom Wikipedia, the free encyclopedia. A cyclic redundancy check ( CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data. Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents. " - Crc8_sae_j1850的多项式
