Rather than answer your question, I'll suggest an alternative. If you need
to implement a CRC algorithm, you may wish to check out:
http://www.dattalo.com/technical/software/pic/crc.php
And in particularly:
http://www.dattalo.com/technical/software/pic/crc_1021.asm
There's an inline assembly routine there that implements the polynomial
you have in your look up table. This routine only takes 18 instructions.
