Challenge Problems

Push your limits with challenges.

Question 1

A system employs a three-level page table organization to handle a 64-bit address space. If each entry is 8 bytes long, calculate the total size required for the page tables if the system requires at least 10,000 pages per level.

💡 Hint: Consider how many entries are needed across all three levels, then multiply by the size of an individual entry.

Question 2

Assess the efficiency of using a hashed page table versus a traditional page table in terms of search time and memory usage given a virtual address space of 2^64 bytes.

💡 Hint: Focus on the efficiency gained by maintaining only the active elements.
