Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Calculate the execution time for a program that has 500,000 instructions, an average CPI of 2.0, and a clock cycle time of 0.1 seconds. What strategies can be employed to decrease this execution time?

💡 Hint: Work through the formula step by step.

Challenge 2 Hard

If a CPU has a clock speed of 3 GHz, what is the clock cycle time? Calculate the performance if the instruction count is 2 million and the average CPI is 1.2.

💡 Hint: Look closely at the conversions and ensure you are correctly employing the formulas.
