Basic Pixel Timing

FONT SIZE : AAA

If there is a space of 25.17 s to handle all of the required pixels, then some basic calculations need to be carried out to make sure that the FPGA can display the correct data in the time available. For example, if we have a 640 × 480 VGA system, then that means that 640 pixels must be sent to the monitor in 25.17 µs. Doing the simple calculation shows that for each pixel we need 25.17 µs/640 = 39.328 ns per pixel. If our clock frequency is 100 MHz on the FPGA, then that gives a minimum clock period of 10 ns, so this can be achieved with a relatively standard FPGA.
