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.

CRC校验码生存程序 校验序列码生成多项式： X16+X13+X12+X11+X10+X8+X6+X5+X2+1 输入数据为16个字节（128位），输出16bit校验序列-CRC, the survival program check sequence code generator polynomial: X16+ X13+ X12+ X11+ X10+ X8+ X6+ X5+ X2+1 input data is 16 bytes (128 bits), output 16bit

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
