Complete answer or none, and please read question:

Calculate the bus bandwidth to display 1280x1024 full-color video at 30 frames/sec. Assume that the data must pass over the bus twice, once from the CD-ROM to the memory and once from the memory to the screen.

Solution

Each frame contains = 1280 * 1024 * 3 [for RGB color]

= 3932160 bytes

In one second, 30 frames are needed

This requires = 3932160 bytes * 30 = 117.96 MB

If the data must travel over the bus twice, the necessary bandwidth

= 2 * 117.96 MB = 235.92 MB/sec.
