xilinx as video processor? |
|
|
Just wondering if the smaller xilinx products are fast enough to do
processing of video signals. ( i know they can handle the complexity )
What i want to do is take RGBI from older computers ( like Atari,
commodore, etc ) and convert them into VGA for a PC monitor..
Ive seen some projects in discrete hardware for a single type of
machine, but never one for several types of machines, and none in FPGA
( goign this route for size and simplicity )
Since we aren't talking drastic resolutions here, i figured they would
be fast enough? |

I would guess so too ... 640x480 is < 30Mhz pixel clock, easily achievable.
Of course that also depends on the treatment but it sounds like all you need
is a timing adaptator ...

Yes, aka scan doubler. No big deal in a Spartan-II(E) or III

Yeah, no problem in current FPGA offerings. HDTV apps are far more
demanding in terms of pixel rate and image size, yet even spartanI
series parts were fast enough for HD apps with enough care taken on the
design.
