Whether or not it made sense at the time, the effect of having reflected algorithms kicking around the world's FTP sites is that about half the CRC implementations one runs into are reflected and the other half not. It's really terribly confusing. In particular, it would seem to me that ...
4 bits is best avoided because it does not correspond to a byte boundary. At the very least, any speedup should allow us to operate at byte boundaries, and in fact most of the table driven algorithms operate a byte at a

CRC对变长的数据块进行计算, 生成一个固定位数的校验值, 典型的 校验和长度是32位或64位, 分别称为 CRC32(32位) 和 CRC64(位). CRC知名的介绍材料是A PAINLESS GUIDE TO CRC ERROR DETECTION ALGORITHMS.对 CRC 本身缺乏了解的, 先移步学习. 计算方式 CRC计算是定义在GF(2)上的二进制除法. 其中被除数是...
计算出的CRC校验码附在原数据帧后面,接收端以模2除法除以多项式,没有余数,则数据无误。 参考文献: A PAINLESS GUIDE TO CRC ERROR DETECTION ALGORITHMS Version : 3. Date : 19 August 1993. Author : Ross N. Williams. 原文网址:http://www.ross.net/crc/download/crc_v3.txt...

其实,在网上有一篇介绍CRC算法的非常好的文章,作者是Ross Williams,题目叫:“A PAINLESS GUIDE TO CRC ERROR DETECTION ALGORITHMS”。我常将这篇文章推荐给向我询问CRC算法的朋友,但不少朋友向我抱怨原文太长了,而且是英文的。希望我能写篇短点的文章,因此就有了本文。不过,我的水平比不了Ross Williams,我的文...
