Consider two different implementations, processor P1 and processor P2, of the same instruction set architecture as described below.

Note that there are four types of instructions (1,2,3 and 4) in the instruction set arch.

P1: clock rate = 700 MHz, CPI1 = 1, CPI2 = 2, CPI3 = 3, CPI4 = 4

P2: clock rate = 850 MHz, CPI1 = 2, CPI2 = 3, CPI3 = 2, CPI4 = 4

Assume that the peak performance is defined as the fastest rate that a processor can execute an instruction sequence chosen to maximize that rate. What are the peak performances of P1 and P2 expressed as the number of instructions executed per second, i.e., MIPS rate? Hint: consider what makes the MIPS rate minimal.
