Question

Consider a program of 15000 instructions executed by a linear pipeline processor with a clock rate of 25 MHZ. Instruction pipeline has 5 stages and one instruction is issued per clock cycle .Calculate speed up ratio, efficiency and throughput of this pipelined processor.

Answer 1

answer:

 

 

Problem 6.1

– Consider the execution of a program of

15,000 instructions

by a

linear pipeline

 processor with a

clock rate of 25 Mhz

. Assume that the instruction pipeline has

five stages

and that

one instruction is issued per clock cycle

. The penalties due to branch instructions and out-of-sequence executions are ignored.a.

 

Calculate the speedup factor using this pipeline to execute the program as compared withthe use of an equivalent nonpipelined processor with an equal amout of flow-through delay. b.

 

What are the efficiency and throughput of this pipelined processor ?
