首先要明确的是CRC只是一种错误检错的码,而没有纠正的作用,那么纠错码可以通过对原数据的+/-/*/÷等进行,但是+/-的问题太大,比如都是对原数据每个bit进行累加运算,如果出错了的话,比如有1bit的1变为0,1bit的0变为1,+/-运算完全识别不出这种错误,显然这种错误除法的辨认概率是非常大的,于是不知道哪位大神...
This tool generates VHDL, Verilog or MyHDL code for use in FPGAs to calculate CRC (Cyclic Redundancy Check) checksums. The generated HDL code is synthesizable and combinatorial. That means the calculation runs in one clock cycle on an FPGA. ...
Java实现循环冗余码(CRC)生成算法一、CRC生成算法原理1.1 多项式编码多项式编码(polynomial code),也称为CRC(cyclic redundancy check,循环冗余校验码),多项式编码的思想是:将位串看成是系数为0或1的多项式。CRC校验保护的单位是数据块。数据块的大小根据实际情况而定。每一个数据块均被看作是一个二进制多项式,即所...
