首先,我们需要一个除数,这个除数可以按照某个行业标准来,比如: IBM的SDLC(同步数据链路控制)规程中使用的CRC-16为:11000000000000101,在ISO HDLC(高级数据链路控制)规程、ITU的SDLC、X.25、V.34、V.41、V.42等中使用CCITT-16为:11000000000100001。 当然这里做个实验,我们也可以随机生成,但是有一点要求,最高位和...

A Model specifies a CRC algorithm: the polynomial, the initial value (resp. optional initial inversion) to be used, and whether a final operation like inversion (XORing) shall be applied. From a static Model, an Inst may be created that allows to calculate a checksum over an amount of dat...
