QRY regarding intel IOP 80331:AAU

Postby jean de henri » Wed Nov 30, 2005 9:15 am

Hi,
Not sure if this is off topic :) but Im trying to use the GF(Q)
multiplication in the AAU for 80331.What is happening for me is that
for a two /3 source descriptor it is simply calculatiing the XOR .
what I see is that the PQ enable bit in the ACR is not getting set :-/
..
here is how it happens
*ACR=0;
*ACR|=(8|1);
*ACR&8 ...fails
it computes the XOR successfully :P


FYI:Im using specs provided in this manual
www.intel.com/design/iio/manuals/304496.htm


Let me know ,
TIA.
Johri
