Suppose the page size is $8$ bytes, the first$-$level page table has $4$ entries and the secondlevel page table has $8$ entries. You need to answer the following questions:

Page Mapping Setup $(30$ marks$)$

A program has three segments that should be loaded and mapped:

Code segment is loaded at physical memory range $[0,24)$ and should be mapped to virtual

memory range $[16,40)$

Data segment: PA $[32,64)$ and should be mapped to VA $[64,96)$

Stack segment: PA $[64,80)$ and should be mapped to VA $[240,256)$

You should fill the physical page frame numbers in the following page tables in Figure $2$ to set up the

page mapping. If some entries in the page tables are not used, you can just leave them empty.

Note: the page directory has been set up$.$ You only need to attach the three filled page tables
