Well, now I'm a lot better, ¡the filter is working! no so good as expected but it is a
start. I took an implementation of an iir filter that comes with the book "Embedded Signal
Processing with the Micro Signal Architecture" and modified it a little to use 32 bits
samples and 32 bits coeff.
I used the 32x32 bit multiply function that comes with the library that is lousy but, still,
it's a start. Now I will have to make a precisse 32x32 bit multiply routine like the one that
is used on the EE186 application note... still have to learn more assambler... can any one give
some help on this? does any one have a good 32 bit multypli routine? does any one knows about a
good book on blackfin assambler?
 
thanks a lot,
 
Juan Carlos Gálvez
