Consider two different implementations of the same instruction set architecture, P$1$ and P$2.$ Processor PI runs on a clock rate of $1\mathrm{.}5GHz$ and $P2$ runs on $2\mathrm{.}0GHz.$ There are fou classes of instructions, A$,$ B$,$ C$,$ and D$.$ The CPIs of each implementation are given in the following table Prganization Computer rganization Computer Organization Computer ganization Computer ganization Computer Given a program with ${10}^6$ instructions divided into the four classes according to the frequencies in the above table. which implementation is faster?
