Question $5.$ Let us consider a computer executing the following mix of instructions:

a$.$ How much is the CPI aver:

How much is the Through

b$.$ Let us assume that, given a HWoptimization technique, the $40\%$ of instructions of the program is executed with $()E$ and the remaining fraction of instructions $(60\%)$ is executed with the same CPI calculated in the case $(1).$

How much is the Speedup from $(1)$ to $(2)?$

How much is the Throughput expressed in MIPS, in the case $(2)?$

c$.$ Let us assume that, given a HW optimization technique, branch and jump instructions require only a single clock cycle.

How much is the Throughput expressed in MIPS, in the case $(3)?$

d$.$ Is it better the optimization introduced in $(2)$ or in $(3)?$
