Challenge Problems

Push your limits with challenges.

Question 1

Given a virtual memory size of 32 bits and a page size of 8 KB, calculate the number of entries in a page table when the page table is stored in memory. Discuss how long it would take to copy this page table to a CPU if each word takes 100 nanoseconds.

💡 Hint: Consider the details of calculating the total entries from virtual memory size and page size.

Question 2

Design an efficient strategy to handle TLB misses in systems with frequent page faults. What might the trade-offs be?

💡 Hint: Think about the balance between complexity and performance when enhancing memory access strategies.
