Re: [oc] Volunteers needed for MAC

[Jamil Khatib <jamilkhatib75@yahoo.com>]

I put the first release of the filter on the CVS you can get teh files
I also updated http://www.geocities.com/jamilkhatib75/ip/da.html

I am still writing teh documents.
I have also some problems with teh testbench.

I want to make teh design more generic faster
It should takes signed numbers and the output size be double the inputs size
I want to write a script to generate system parameters and constants

If some one is intrested let me know

Thanks
Jamil
