Consider two different implementations of the same instruction set: CPU1 and CPU2. This instruction set has five classes (A, B, C, D, and E) of instructions whose CPIs for each CPU are given in the table below. CPU1 has a clock rate of 2.50 GHz, and CPU2 has a clock rate of 3.00 GHz

a. If peak performance is defined as the fastest rate that a computer can execute any instruction sequence, what are the peak performances of CPU1 and CPU2 expressed in instructions per second?

b. If the number of instructions executed in a certain program is divided equally among these instruction classes except for class B, which occurs twice as often as each of the other classes, which implementation is faster (i.e., CPU1 or CPU2), and by how much?
