I came across this app. notes while started working on a project that needs a small but fast CRC routine.

I talked to my friends and colleges, and tried to search the WWW. But could only find the table driven one or the slow bit shifting one. Until I found that app. notes.

It took me a while to understand how it works. The first one to come up with this function is really really clever.

I am considering how to make it works with different polynormials, but not sure if there is any copyright/patent issues.

I learned a lot here and think it is good to share with others. Anyone interested in doing that for this forum?
