4 bit CRC
"Everything you wanted to know about CRC algorithms, but were afraid to ask for fear that errors in your understanding might be detected."
That's the subtitle to a very informational web book on CRCs in general. A PAINLESS GUIDE TO CRC ERROR DETECTION ALGORITHMS
There's tons of resources for more standard long CRCs for big machines, but I'm interested in a four bit CRC I can cram into my 128 data bit messages processed by a little 8051. "CRC Selection for Embedded Network Messages" is a *great* paper that lays out the trade offs between number of CRC bits / data bit length / level of protection, and gives a table with the breakpoints for each. This is computer science doing good for practicing engineers.
