$2.$ In this exercise, we examine how pipelining aff ects the clock cycle time of the processor. Problems

in this exercise assume that individual stages of the datapath have the following latencies:

Also, assume that instructions executed by the processor are broken down as follows:

$1)$ What is the clock cycle time in a pipelined and non$-$pipelined processor?

$2)$ What is the total latency of an LW instruction in a pipelined and non$-$pipelined processor?

$3)$ If we can split one stage of the pipelined datapath into two new stages, each with half the

latency of the original stage, which stage would you split and what is the new clock cycle

time of the processor?

$4)$ Assuming there are no stalls or hazards, what is the utilization of the data memory?

$5)$ Assuming there are no stalls or hazards, what is the utilization of the write$-$register port of

the $$Registers$$ unit?
