CRC循环校验码的生成。文件里是（40，32）的校验码生成电路，采用串行输入、串行输出的方式。-CRC checksum generation cycle. File is (40,32) of the check code generation circuit, the use of serial input, serial output mode.

赛灵思的循环冗余校验（CRC），内服详细说明-The Cyclic Redundancy Check (CRC) is a checksum technique for testing data reliability and correctness. This application note shows how to implement Configurable CRC Modules with LocalLink interfaces. Users tailor the modul
