Framebuffer guesses
How many bits per pixel?
- 4MB = 32Mb (Megabits)
- 32Mb/ (800x600) => 69 bits per pixel, round down to 64 bits (5 wasted bits per pixel)
64 bits/pixel
- 16 bits front buffer
- 16 bits back buffer
- 16 bits Z-buffer
- 16 bits left for misc functions
Assume 64 bit datapath to Framebuffer
