- A machine has a 16-bit byte-addressable virtual address space. The page size is 8 KB. How many pages of virtual address space exist? (25 points)
Homework Answers
Given:
Virtual Address size of the machine: 16bits
Page Size : 8Kb
Thus, before calculating each address is to converted into the number of bytes
Therefore
Virtual address size = 2^16 bytes
Page Size = 2^13 bytes
Now using the formula
Number of entries in page table = (virtual address space size)/(page size)
Number of pages = (2^16)/(2^13) = 2^3
Thus,
Number of pages of virtual address space = 2^3

A computer system has a 36-bit virtual address space with a page size of 8K, and 4 bytes per page table entry. How many pages are in the virtual address space? What is the maximum size of addressable physical memory in this system? If the average process size is 8GB, would you use a one-level, two-level, or three-level page table? Why? Compute the average size of a page table in part c above
