Suppose a processor P has a 2.5 GHz clock rate and a CPI of 1.5. We are trying to reduce the execution time by 20%, but this leads to an increase of 20% in the CPI. What is The clock rate we should have to get this time reduction?

Question: Suppose a processor P has a 2.5 GHz clock rate and a CPI of 1.5. We are trying to reduce the execution time by 20%, but this leads to an increase of 20% in the CPI. What is The clock rate we should have to get this time reduction?

 

 

Question: Assume that for a program, compiler C results in an instruction count of 20000 and has an execution time of 50 microseconds. Given that the processor has a clock cycle of 2 ns, what is the average CPI?

 

Question: Continue from the previous question. If a new compiler is developed that uses only 15000 instructions and has an average CPI of 1.3. What is The execution time of using the new compiler on the original processor?
