Hi,
I am trying to sample an 80 Mhz video signal from an ADC. Obviously, my 12 Mhz LPC can't handle this. Is there a way to slow it down to take a full frame at a time, and ignore the ones it can't grab.
My only other option is a Xilinx chip to buffer the data, and allow the LPC to fetch it from Xilinx as fast as it can.
I need a video stream. Obviously not at a high frame rate, but usable.
No way are you going to pass anything resembling a usable video stream through a CPU running at 12 MHz.
1280x1024x(R8,G8,B8)@10fps is still more than 30 MBytes/s, and video at less than 10 frames per second is unusable.
