Consider two processors P1 and P2 with four types of instructions as listed in the table. 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.

Which implementation (P1 or P2) is faster? What is the overall CPI for each implementation P1 and P2? 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
