15- a) What are the drawbacks of Programmed V/O and interrupt driven /O? : Explain how DMA overcomes these drawbacks.
- b) Prove that “Speedup factor for pipelined processor is equalto number of stages in pipeline.” Assume that pipeline has K = 6 segment and execute n = 120 tasks in a sequence. Let the time taken to process the sub-operation in each segment is 30ns. Calculate the speedup ratio.
