Consider a processor has virtual address 52 bits, the physical address is 32 bits and page size is 16KB. Each individual table at any level of the page table occupies a single page of physical memory. Using multi level paging, how many entries are there in each individual page table page. Consider page table entry requires additional 14 bits for special purpose?

<4,12,12,12>
< 2, 12, 12, 12 >
<4,14,14,14>
<10,12,14,14>

@ gauravkc i mean in Ashwin Comment he did

No Of Frames = Virtual Memory / Physical Memory

but i have learnt that Physical Memory / Frame Size....i just want to know what is logic behind that..?

He did that only. Where do you see VM / PM :o

2³² is PM and 2¹⁴ is FS
