james1095 Posted April 11, 2013 Report Share Posted April 11, 2013 Better resolution than what? The most common that I've seen used with FPGAs is 640x480 with the Papilio VGA wings capable of up to 4096 colors. While VGA does include a 320x200 resolution, that hasn't been common since the era of DOS games. Link to comment Share on other sites More sharing options...
hamster Posted April 11, 2013 Report Share Posted April 11, 2013 If you want to do monochrome bit-mapped graphics on a -500 part you have 368,640 bits of block RAM, so just enough for 640x480. If you want to do tile-based graphics (e.g. have a choice of 256 x 8x8 tiles, with 8 bit colour per pixel) You could use 16,384 bytes for the tiles, then another 14,400 bytes to hold a 160x90 map of what tiles are in use, giving a 256 colour 1280x720 output.

Jack Gassett Posted April 12, 2013 Report Share Posted April 12, 2013 Alvie was working on higher resolutions with the extra SDRAM available with the Papilio Pro. Jack. Link to comment Share on other sites More sharing options...
