2. Consider two processors P1 and P2 with four types of instructions as listed in Table 1. Assume that a program with a dynamic instruction count of 106 instructions such that the instructions are divided into the classes as follows: 10% class A, 20% class B, 50% class C, and 20% class D. a. Which implementation (P1 or P2) is faster? b. What is the overall CPI for each implementation P1 and P2? c. Find the clock cycles required for both processors. CPU/CPI Class A Class B Class C Class D P1(2.5 GHz) 1 2 3 3 P2(3.0 GHz) 2 4 2 3 Table 1 Clock per instruction for each class off instruction
