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: Generate a simple 640x480 VGA test pattern with all timing and sync signals controlled by the FPGA. (DONE)
2: Add a 24-bit color gradient to the test pattern with the addition of a THS8134B video DAC on the output.
3: Create a dual framebuffer in the devboard's SRAM.
4: Use the framebuffer to display low resolution (<640x480) 24-bit digital video input within a 640x480 output frame without scaling.
5: Attempt to implement scaling algorithms to scale the input resolution to fill the full frame of the output resolution.
If I can manage to get this far, I will add additional objectives.
