Mapping between virtual and physical address in memory paging -


in system, paging mapped virtual address (a8b43f​​)16 physical address (13efd43f)16.

what can inferred page size?

while not enough information determine certain, can infer upper limit on page size noting lower 13 bits of both addresses same. know page index lower x bits of address, if find maximum page index, can determine maximum page size. 0x00a8b43f , 0x13efd43f share same lower 13-bits ('b1_0100_0011_1111). thus, maximum page size can 2^13 words, or 8 kwords. if memory byte addressable, means page size of 8kb.

however, without more information, knowing exact page size not possible shared bits might have come convenient mapping.
