Problem $4.$ Multi$-$level page tables

rve perfected my machine's page table implementation. I need you independenthy verify my

implementation. Note: rve expressed all of the numbers in binary. Ive decided to use $4$ bits

for rry page offset and $6$ bits for virtual page number. The mast significant $3$ bits are used to

index the page directory and the next $3$ bits are used to index the corresponding page table.

Virtual Address:

Your mission: Given a virtual address and a type of access $($Read$,$ Write, eXecute$),$ determine

the physical address accessed. If the translation fails or the permissions do not allow that

type of access, the correct answer is FAULT. If the translation succeeds and the access type is

permitted, the correct answer is the entire physical address to be accessed by the MMU $($pag

frame number and offset$].$

Multi$-$level page tables, continued.

Given rry choices for virtual page number length, how big is rry virtual address space in

pages? In bytes?

How big is my physical address space in pages? In bytes?
