Example 1: Determine the number of memory bits essential for three bit plane frame buffer for the 512 x 512 raster
Solution: Whole memory bits needed are 3 x 512 x 512 = 786,432
Example 2: What is the refresh rate in the 512 x 512 raster if pixels are accessed at the rate of 200 nano-seconds?
Solution For particular access of pixels rate is 200x10-9 seconds for 512x512 pixels. 0524 seconds needed.
Refresh rate per second is 1/0.0524 =19 frames/seconds.
