Question
A graphic display system has a frame buffer that is 640 pixels wide, 480 pixels high and 1 bit of color depth. If the access time for each pixel on the average is 200 nanoseconds, then the refresh rate of this frame buffer is approximately:
The correct answer is
16 frames per second
\(T=640\times480\times200\times10^{-9}=0.06144\ \mathrm{s}\)
\(f=\frac{1}{T}\approx16.28\ \text{frames/s}\)
The nearest option is 16 frames per second.
