1. When run on a given system, a program takes 900,000 clock cycles. If the system achieves CPI of 35, how many instructions were executed in running the program?

2. What is the IPC of a program that executes 30,000 instructions and requires 180,000 cycles to complete?

3. If the 2005 version of a computer executes a program in 140 sec and the 2010 version of the same computer executes the same program in 110 sec, what is the speedup that the manufacturer has achieved over the five year period?

4. To achieve a speedup of 3 on a program that originally took 78 sec to execute, what must the execution time of the program be reduced to?
