Slow frame rate (DE1 + D5M)

Has anyone solved this problem?

I too have a slow frame rate with D5M and DE1

I connected the d5m camera to the de1 board and loaded the DE1_D5M project. When I plug the vga connector I can see images, but with a very slow rate. If I increase it (sw0 + key1) the image quickly become black, but still with a low frame rate.

In the hardware spec. it is said that the camera can take 150 frames per second at vga, while I'm seeing less than 10 fps.

I thought that the reason could be some slowness in the vga part of the circuit, and to verify this I debugged (jtag in-system probe) the rCCD_FVAL line, which should be the "frame valid" signal coming from the camera. This line shows the same slow frame rate.

Any hint?

My actual need is to do image processing on a row-by-row basis, of frames coming at, say, 30..60 per second.
