There are, however, some cool things you could do with audio.
Obviously, the DACs are way overkill for audio. You can do audio with
a digital signal and a low-pass filter. So we can make a simple board
with caps and inductors on it that turns this into a 60-channel audio
board. :)
One thing you could possibly do, but you have to be careful about
violating local laws, is use the video DAC to cheaply modulate a
kilohertz carrier wave. That is, you have logic in the FPGA that's
generating a sine wave on the output and adding modulation to it. You
could do AM, FM, or PM. To transmit a signal, all you'd need it a
powerful amplifier. Use it to transmit your MP3's from your computer
to every stereo in your house. :)
Forgetting the output stuff, we've got 72 multipliers. How about
doing digital signal processing? Both audio and video. Once the PCI
controller is finished, just use it to shuttle data back and forth for
expensive computations. [EMAIL PROTECTED] anyone?

Hello,
I am a software developper and I have almost no knowledge of FPGA
programming but I am interrested in OGP for different reasons. Now, if
I understand the situation correctly, if I want to develop programs that
use OGD1 I will need :
1) a board (of course).
2) a driver so that the OS (Linux in my case) can access the card.
3) some modules that will be loaded into the FPGA.
4) A program/ A tool to load the modules into the FPGA
5) some API/libraries to access the functionalities of the loaded
module(s).
Is this correct ?
If this is correct, it would be great to have a repository of open
modules written by hardware specialists so that the 'normal' software
developper can choose and the download the ones he needs.
I recently found this website :
http://www.gpgpu.org/
General-Purpose Computation Using Graphics Hardware. It could be
interresting to send them a note on OGP. Maybe OGD1 will not interest
them. But OGC, with its open specifications, will certainly.
Bernard.
