![]() ![]() Pixel clock, so I instead run-length encoded the image data and dropped theīits per pixel down to a four bit value that could then used in a color table The only problem was that aīig enough to hold a 640*480 screen requires 307kB of buffer space, and theīoard didn’t have any external RAM memory, and the Artix-735Tīoard didn’t have enough block RAM for such a buffer.Įventually, I settled on an approach that used a 25MHz pixel clock and You know, get the most for your money? Hence the question, how best should I ![]() ![]() ![]() As a new student of FPGA design, and particularly one on a budget, I wanted to create a series ofĭesigns that would eventually use all of the hardware ports of that board.
