Question: Three instruction types or classes exist: C 1 , C 2 , C 3 On Machine M 1 clocked at 3.7 GHz, the following measurements
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 ?
