There are four classes of instructions, A, B, C, and D. The clock rate and CPI of each implementation are given in the following table. Clock Rate CPI Class A CPI Class B CPI Class C CPI Class D i. P1 2.5 GHz 1 2 3 3 P2 3 GHz 2 2 2 2 ii. P1 2.5 GHz 2 1.5 2 1 P2 3 GHz 1 2 1 1 (a) [10 points) Given a program with 106 instructions divided into classes as follows: 10% class A, 20% class B, 50% class C, and 20% class D, which implementation is faster? (b) (5 points] What is the global CPI for each implementation? (c) [5 points] Find the clock cycles required in both cases. The following table shows the number of instructions for a program
