The below table shows three different processors $P1,P2,$ and $P3$ running three

programs and their corresponding clock period, CPI, and Instruction Count $($IC$)$ are given below. Showing all the steps, answer the following. Make sure all the answers

are rounded off to the nearest hundredth or two decimal places.

a$.$ Compute the CPU time for each of the programs running on P$1,$ P$2,$ and P$3.(9$

Points$)$

b$.$ If a new program that has $2,500$ instructions is run on processors $P1,P2,$ and $P3,$

which processor $($P$1,$ P$2,$ or P$3)$ has the best performance in terms of CPU time

and why? Assume the new CPIs as $3\mathrm{.}00,4\mathrm{.}00,$ and $1\mathrm{.}50$ when the program is run

on processors P$1,$ P$2,$ and P$3$ respectively. $(10$ Points$)$
