4 cards from this section. Quick, good the night before a test.
What are the two parts of a virtual address?
Think about how memory is identified.
What does the valid bit in a page table entry indicate?
Consider what happens if the valid bit is 0.
What are the two main components of a virtual address?
Recall the structure of a virtual address.
True or False: A valid bit of 1 indicates that a page is present in physical memory.
Think about what happens when this bit is not set.
Given a 64-bit architecture with a page size of 8KB, calculate the maximum number of entries in the page table and the physical memory required.
Think about how to derive page entries from addressable space and page sizes.
How would you design a page replacement algorithm to optimize memory usage when accessing virtual addresses? Explain your approach.
Consider which pages are most likely to be accessed again and how you might keep track of them.
