A 956 x 1290 pixel grayscale image with each pixel able to display 32 shades of gray. How long would it take to transfer this image over a DMA channel with 2.5 Gbps (bps = bitspersecond) ?

Expert Solution
Step 1

Answer:

Step 1:

Each display has 32 shades of gray,

25=32

so, the bit depth is 5

Step 2:

Compute size of the display:

(number of pixels)×bit depth956×1290×56,166,200 bytes
