Challenge Problems
Push your limits with challenges.
Question 1
Calculate the total CPU time for a program with 100 instructions, with 1.1 CPI, and 20 memory stalls (each costing 50 cycles).
💡 Hint: Use the formula for CPU time.
Question 2
Given a system with 70% modified pages causing a 20 ms wait and 30% unmodified causing a 10 ms wait, calculate the average time to handle a page fault if 1% of memory accesses cause faults.
💡 Hint: Break the problem into two parts: handling dirty vs. clean pages.
