Consider a 64-bit architecture machine where physical memory is 32GB. a. If we would like to run processes as big as 128GB how many bits would be required for the logical address? b. If we are using pages of size 16KB, how many bits are needed for displacement into a page c. If a single level page table is used, what is the maximum number of entries in this table? d. What is the size of this single level page table in terms of 16KB pages e. If a two-level page-table is used and the outer page table is an 16KB page, how many entries does it contain, maximally? f. How many bits of the logical address are used to specify an index into the inner page (page of page table)
