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. What is the relative speedup of P₁ on M₁ versus P₁ on M₂ and which is fastest: P₁ on M₁ ; P₁ on M₂ ; P₂ on M₁ ; or P₂ on M₂??
