Video memory: size, transfer rate

A 1024 x 768 image is displayed, non interlaced, at a rate of thirty frames per second.

a. If the image is stored with 64-k color resolution, which uses 2 bytes per pixel, how much memory is required to store the picture?

b. How much video memory is required to store the picture as a "true color" image, at 3 bytes per pixel.

c. What is the transfer rate, in bytes per second, required to move the pixels from video memory to the screen for the "true color" image?

Solution Preview

a. Memory required to store the picture with 64-k color resolution = (1024*768) pixels * 2 bytes/pixel = 1572864 bytes or 1536 KB

b. ...
