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

4.1 Amdahl's Law

4.2 On M₁ and M₂, assume C₂ type instructions can be accelerated up to 4 times faster.

>> How much do C₂ type instructions have to be accelerated (or decelerated) on M₁ versus M₂ to make P₁ on M₁ run as fast as P₂ on M₂ ?
