Hello NG,

I coded a CRC16 CCITT algorithm that does well for 16 bit integers. I
did it just how the guys at the college explain it.
(http://www.mikrocontroller.net/wiki/CRC - in german -)

But how do you efficiently implement a CRC algorithm for large data,
like files etc.? I heard sth. about splitting it to data words and
XORing their CRCs? I don't know, please explain me.

Thanks in advance,

Arwed
