Question 1 : Suppose I need 10 bits to specify the offset within a page and 22 bits to specify the virtual page number and 18 bits to specify the physical page number.
How big is a page in bytes?
How big is the virtual memory address in bits?
How big is the physical address in bits?
Question 2 : A system has a 46-bit virtual address. 24-bit physical address, and 2^20 Bytes of main memory. If the page size is 29 = 512 bytes answer the following questions:
How many virtual pages are there?
How many physical pages will the system support?
How many page frames are there in main memory?
Suppose the memory management system does compaction to reduce the holes in memory space.
If the compaction is ideal what is the size of the largest hole that can exist on this system?
