Consider two different implementations, $P1$ and $P2,$ of the same instruction set. There are five classes of instructions $(A,B,C,D,$ and $E)$ in the instruction set. P$1$ has a clock rate of $4GHz,$ and $P2$ has a clock rate of $6GHz.$ The average numher of cycles for each instruction class for P$1$ and P$2$ are listed in the following table.
