Q$5)[5$ points$]$ Consider two different implementations, $M1$ and $M2,$ of

the same instruction set. There

are three classes of instructions $($A$,$ B$,$ and C$)$ in the instruction set. M$1$

has a clock rate of $80MHz$ and

$M2$ has a clock rate of $100MHz.$ The average number of cycles for each

instruction class and their

frequencies $($for a typical program$)$ are as follows:

$($a$)$ Calculate the average CPI for each machine, M$1,$ and M$2.$

$($b$)$ Calculate the average MIPS ratings for each machine, M$1$ and M$2.$
