5. Suppose that a machine has 38-bit virtual addresses and 32-bit physical addresses. a) What is the main advantage of a multilevel page table over a single-level one? b) With a two-level page table, 16KB pages, and 4-byte entries, i. How many bits should be allocated for the top-level page table field? ii. How many bits should be allocated for the next level page table field?

Q: Assigning the first element of an array is done by

A: An array is a collection of elements of the same type placed in continuous memory location. Example…

Q: Give the number of the virtual page that the byte with virtual memory address 52000 belongs to,…

A: Page size = 8KiB This means page offset = log 8KiB = 13 bits So the least significant 13 bits will…

Q: 2) A memory system has a page size of 1024 (2¹0), four virtual pages, and three physical page…

A: Page size = 1024(2 10) virtual page = 4 Physical page frames = 3

Q: ry split into pages. If each byte in the virtual memory has a virtual address, and the last 8 bits…

A: Pages are typically 512 to 8192 bytes in size, with 4096 being the most common value. For reasons…

Q: Assume we have a page table when some pages aren’t in main memory. Is there any occurrence of page…

A: Answer : yes  , there will be  occurrence of page faults. As this is because page faults only occur…

Q: Suppose that an MMU has page table entries like the ones shown at right (formatted as in the slides…

A: The solution of the above question is:

Q: Consider the following portion of a page table from a system with 4 KiB (i.e., 4096 byte) pages.…

A: We have given portion of page table and page size is 4KiB. Using virtual memory address, we have to…

Q: We design a 2-level page table scheme. The size of each page is 4K bytes. Given the 32-bit virtual…

A: Size of page = 4KB Now total number of pages = 232/212 = 220
