I've decided to start a separate blog for checksum and CRC postings. There are only a few posts at this point, but I expect it will accumulate quite a bit more material over time.
http://checksumcrc.blogspot.com/
Checksum and CRC Central: Cyclic Redundancy Codes, Checksums, and related issues for computer system data integrity.
The most recent post gives CRC polynomials for optimal protection of 8-bit, 16-bit, and 32-bit data words such as you might want for ensuring integrity of key variables. The blog you're reading now (Better Embedded System SW) will continue as before.
Here's wishing everyone a happy and prosperous new year!
