**Video scaler with VGA output**
|
|
|
|
|
|
|
|
|
|
To reduce the high likelihood of this project ending in undebuggable
|
|
|
|
|
disaster, I plan to start off with simple goals and add complexity to
|
|
|
|
|
the code and input/output circuitry incrementally.
|
|
|
|
|
|
|
|
|
|
1: (COMPLETED) Generate a simple 640x480 VGA test pattern with all
|
|
|
|
|
timing and sync signals controlled by the FPGA.
|
|
|
|
|
|
|
|
|
|
3: Create a framebuffer in Block RAM or the devboard's SRAM.
|
|
|
|
|
|
|
|
|
|
4: Use the framebuffer to window low resolution (\<640x480) digital
|
|
|
|
|
video input within a 640x480 output frame (no scaling).
|
|
|
|
|
|
|
|
|
|
5: Attempt to implement scaling algorithms to scale the input resolution
|
|
|
|
|
to fill the full frame of the output resolution.
|
|
|
|
|
|
|
|
|
|
6: Add 24-bit color depth to the output with the addition of a THS8134B
|
|
|
|
|
video DAC.
|
|
|
|
|
|
|
|
|
|
If I can manage to get this far, I will add additional objectives.
