Challenge Problems
Push your limits with challenges.
Question 1
If a processor executes 10 billion instructions with a base CPI of 1.5 and experiences a 15% miss rate leading to a 30-cycle miss penalty, calculate the total execution time.
💡 Hint: Break the problem down into base execution and miss contributions.
Question 2
Discuss how you would design a page replacement algorithm to minimize page faults while considering the costs of writing dirty pages. What factors would you weigh?
