| Modules use excessively high memory resources when synthetising with Vivado. Versions 1.2 and above should soon fix this issue soon. Til then, 640x480 resolution can only be achieved at 8 bits/Pixel. (9 bits/pixel might work but was not tested, please give feedback concerning this limitation). | Modules use excessively high memory resources when synthetising with Vivado.
