We are looking for a frame grabber that can simultaneously:
1 Grab one frame (monochrome, 512 x 512 x 8, 25 frames/second)
2 Display another frame
3 Have a 3rd frame modified by a host computer
4 Transfer the frame that is being grabbed to a custom
  co-processor board with DSP (of our design) through a
  dedicated port

The frame grabber must have storage for at least 3 frames
Requirement 4 can be relaxed to
  transfer a 4th frame to a custom co-processor board...
but then we need storage for at least 4 frames in the frame
grabber.

It would be nice if the frame grabber fits inside an PC/AT, but
VME based solutions are also acceptable.

We have been looking at boards manufactured by Data Translation, 
but these are unable to grab and transfer simultaneously.
