Consider two different implementations, M$1$ and M$2,$ of the same instruction set. There are three

instruction types: A$-$type, B$-$type, and C$-$type. M$1$ has a clock rate of $2$GHz$,$ and M$2$ has a clock rate of

$2\mathrm{.}2$GHz$.$ The average number of cycles for each type of instruction, as well as their frequencies, are

given below. Calculate the average CPI for each machine, M$1$ and M$2.$

Instr. Type M$1$ Cycles per Instr. Class M$2$ Cycles per Instr. Class Frequency

A $2360\%$

B $3230\%$

C $3110\%$
