- Three different processors P1, P2, and P3 execute the same instruction set. P1 has a 2.5 GHz clock rate and a CPI of 1.0. P2 has a 3.0 GHz clock rate and a CPI of 1.5. P3 has a 3.5 GHz clock rate and has a CPI of 2.2.
- Which processor has the highest performance expressed in instructions per second?
-
- If each processor executes a program in 12 seconds, find the number of cycles and the number of instructions.
-
- We are attempting to reduce the execution time by 30%, which leads to an increase of 20% in the CPI. What clock rate do we need in order get this time reduction?
