PERFORMANCE CALCULATION

Three instruction types or classes exist: C1, C2, C3

On Machine M1 clocked at 3.7 GHz, the following measurements hold:

C1has CPI1 = 1.2 ; C2has CPI2 = 2.3 ; C3has CPI3 = 3.4 cycles/instruction

On Machine M2 clocked at 4.6 GHz, the following measurements hold:

C1has CPI1 = 2.7 ; C2has CPI2 = 3.6 ; C3has CPI3 = 4.5 cycles/instruction

Program P1 has 456 Type 1 instructions, 567 Type 2 and 6685 Type 3 Instructions

Program P2 has 499 Type 1 instructions, 598 Type 2 and 6043 Type 3 Instructions

3. How fast must M₁ be clocked to make P₁ on M₁ as fast as P₂ on M₂?
