Hi,
I'm also an electrical engineering student and my current praticum
exercise is to build an micro processor in an Xilinx FPGA (Spartan 2).
I've such a thing on university, but since it's in a box, I don't have
very much capabilities to use it to build some DSP thing. I do have the
software to design chips and upload it all into the FPGA.
From my experience it's horrible to work wit hthem, becuase they hardly
ever work. (Might be my experience with them, or the low quality software
we got from uni).
But what is ti you guys want to build? An soundcard with on board DSP for
SB Live! like fun or do you want to design your own DSP?
I think it's best to use a standard DSP and make a soundcard using it, so
that's user programmable, might be intern or extern, just what's
easier/cheaper.
BTW, if such a project really starts, I like to join.
