the best i have found being the one in info-zip (3,75 instructions/byte with x4 unrolling)

Ok I thought that was a CRC operation for the F-cpu. Just remember you need to calculate a 16 bit look up table. C is great for that. :)

However, my application needs CRC16 so i can't simply copy-paste info-zip's source code.
but don't worry for me, i'm not too bad in asm programming.

Better than 8088 asm programing. :( I did this years ago with 8 bit CRC ??? with refernce from BYTE.
