Question: 2. (10 points) Consider two machines with two different instruction sets. Machine A has a 2 GHz clock, and machine B has a 4 GHz
2. (10 points) Consider two machines with two different instruction sets. Machine A has a 2 GHz clock, and machine B has a 4 GHz clock. The following measurements are recorded upon execution of a program.
| Machine A | Instruction Class | ||
| Arithmetic | Load/Store | Branch | |
| Instruction Count (millions) | 10 | 4 | 6 |
| CPI | 2 | 3 | 1 |
| Machine B | Instruction Class | ||
| Arithmetic | Load/Store | Branch | |
| Instruction Count (millions) | 14 | 5 | 8 |
| CPI | 2 | 8 | 1 |
For Machine A, what is the average CPI and execution time?
For Machine B, what is the average CPI and execution time?
