Computer Architecture

4. Consider two different implementations, PI and P2, of the same instruction set. There are five classes of instructions (A, B, C, D, and E) in the instruction set. PI has a clock rate of 4 GHz. P2 has a clock rate of 6 GHz. The average number of cycles for each instruction class for PI and P2 is as follows: Class CPI on PI CPI on P2 4 Assume that peak performance is defined as the fastest rate that a computer can execute any instruction sequence. What are the peak performances of Pl and P2 expressed in instructions per second? 2 pts]
