(2HS+52HB+320+8HF) x (2VS+5VB+240+4VF) We artificially extend the Vertical Front Porch so CPU can update frame buffer: Dot Clocks per Frame = 225,762 clocks.(2hs+52hb+320+8hf) x (2VS+5VB VF) Final Dot Clock Rate = 11.3 MHz [ 225,762 dot periods x 50 fps ] VGA (640 x 480), 16 bpp, 35 fps Frame buffer size = 614 Kbytes Extended Dot Clocks per Frame = 498,960 clocks Dot Clock Rate = 17.5 MHz 19
