1. Anna designs a 2.5 GHz processor where two important programs, A and B, take onesecond each to execute. Each program has a CPI of 1.25. Elsa is tasked with designingthe company's next-generation processor and she comes up with an idea that improvesthe CPI of A to 1.1 and the CPI of B to 0.9. But the idea is so complex that theprocessor can only be implemented with a cycle time of 0.5 ns. Does Elsa's newprocessor out-perform Anna's processor on program A? How about on program B?2. Consider two different implementations of the same instruction set architecture. Theinstructions can be divided into four classes according to their CPI (class A, B, C, andD). P1 with a clock rate of 2.5 GHz and CPIs of 1, 2, 3, and 3, and P2 with a clockrate of 3 GHz and CPIs of 1, 2, 2, and 2.Given a program with a dynamic instructioncount of 106 instructions divided into classes as follows: 10% class A, 20% class B,50% class C, and 20% class D, which is faster: P1 or P2?
