A 100 MHz processor is connected to a device through a DMA controller. Assume that the initial set-up of DMA takes 100 clock cycles. The device has a transfer rate of 200 Kbytes/sec and average block size transferred is 4 KB. What fraction (in %) of the processor time is consumed by the device.
  • a)
    0.05
  • b)
    0.15
  • c)
    0.015
  • d)
    0.005

Verified Answer
A 100 MHz processor is connected to a device through a DMA controller....
Cycle time of processor = = 10ns
Processor time = 100 x 10ns = 1ߎs
Data transfer time = = 20ms
% of processor time consumed by the device
= = 0.005
