Virtual Memory

Consider a Virtual Memory System with the following properties:

48-bit virtual address space

32-bit physical address (4GB)

16 Kbyte pages

a) What is the total size of the Page Table, in bits, for each process on this machine, assuming that the Valid, Protection, Dirty and Use bits take a total of 4 bits and that all the virtual pages are being used?

b) The Virtual Memory system is implemented with a two-?way set associative TLB with a total of 256 entries (128 sets). Describe the Virtual Memory address organization (i.e. how the address bits are partitioned for address translation) and the process of mapping an address from the Virtual Memory space to the Physical Memory space.
