Consider two different implementations of the same instruction set architecture. The instructions can be divided into four classes according to their CPI (class A, B, C and D). P1 with a clock rate of 3GHz and CPIs of 3, 2, 1, 4, and P2 with a clock rate of 2.5GHz and CPIs of 2, 2, 2, 2. Processor Class A Class B Class C Class D P1 3 2 1 4 P2 2 2 2 2 Given a program with a dynamic instruction count of 1.0E5 instructions divided into classes as follows: 10% class A, 30% class B, 40% class C, and 20% class D. Which implementation is faster? What is the global CPI for each implementation? Find the clock cycles required in both cases?
