Consider three different processors, P$1,$ P$2,$ and P$3,$ executing the same ISA.

P$1$ has a CPI of $2\mathrm{.}5$ and can execute $1\mathrm{.}8109$

instructions per second.

P$2$ has a CPI of $2\mathrm{.}2$ and can execute $2109$

instructions per second.

P$3$ has a CPI of $1\mathrm{.}5$ and can execute $2\mathrm{.}5109$

instructions per second.

i$)$ What is the clock rate of P$1,$ P$2$ and P$3?$

ii$)$ If P$1,$ P$2$ and P$3$ execute a program in $6,8,12$ seconds individually, find the number of

cycles for each processor.
