In a main memory-disk virtual storage system, the page size is 1KByte and the FIFO algorithm is used for page replacements. A given program has been allocated three page frames in the main memory and it makes the following 16 memory references when it starts executing (the addresses are given in decimal):500, 2000, 2500, 800, 4000, 1000, 5500, 1500, 2800, 400, 5000, 700, 2100, 3500, 900, 2400 Fill in the contents of the three page frames after each memory reference in a table and calculate the hit ratio. Hint: denote by 'a' the page consisting of locations 0 through 1023 in memory. Similarly, b: 1024-2047, c: 2048-3071, d: 3072-4095, e: 4096-5119 and f: 5120-6143. Round to three decimal places.
In a main memory-disk virtual storage system, the page size is 1KByte and the OPTIMAL algorithm is used for page replacements.

With virtual memory, when a program requests memory,the memory management system does which of the following? Select one: A. It grants the request as long as there is enough physical memory to accommodate B. It looks up the address in the page table. If the address is in memory, then it grants the request. C. It looks up the address in the page table. If the address is in memory, it grants the request. If the address is stored to disk, it writes a section of memory to disk and then transfers the requested virtual memory address from disk to main memory. D. It causes a deadlock to occur.
Consider an operating system that uses 48-bit virtual addresses and 16KB pages. The system uses a hierarchical page table design to store all the page table entries of a process, and each page table entry is 4 bytes in size. What is the total number of pages that are required to store the page table entries of a process, across all levels of the hierarchical page table?
For this assignment, you are to write a MIPS assembly language program using the MARS IDE and assume a system has 31-bit virtual memory address (so no worry about negative numbers) with a 4-KB page size (4096 bytes). Write a MIPS program that accepts an integer input that represents a virtual address and outputs the page number and offset for the given address in decimal. The output should look like: The address 19986 is in: Page number = 4 Offset = 3602 Check to make certain your program works. You can use the output from 19986 given above as a test, but I will use other numbers to test it. Submit the MIPS assembly language code and a screenshot showing a test run.

I have a 128-bit computer where addresses are 128 bits wide. I want to implement virtual memory with paging for this computer, and I want to use a page size of 4KB. I will design it so that a page table consumes exactly one page. How many page table entries (PTEs) fit within a page?

Part A For each byte sequence listed, determine the Y86 instruction sequence it encodes. If there is some invalid byte in the sequence, show the instruction sequence up to that point and indicate where the invalid value occurs. For each sequence, the starting address, then a colon, and then the byte sequence are shown. 0x100: 30f3fcfffff40630008000000000000 0x100: 30f3fcfffffff irmovq $-4,%rbx Ox10a: 40630008000000000000 | rrmovq %rsi,0×80A(%rcx) O0x115: 00 halt Ox100: 30f3fcffffffff irmovq $-4,%rbx Ox10a: 40630008000000000000 | rmmovq %rsi,0x800(%rbx) Ox114: 00 halt 0x100: 30f3fcfffffffff rrmovq $-8,%rbx Ox109: 40630008000000000000 | rmmovq %rsi,0x800(%rbx) 0x200: a06f800c020000000000000030f30a00000000000000 0x113: 00 halt 0x100: 30f3fcffffffffff irmovq $-4,%rbx 0x200: a06f pushq %rsi 0x10a: 40630008000000000000 | rmmovq %rsi,0x800(%rbx) Ox202: 800c02000000000000 call proc Ox116: 00 halt 0x20b: 00 halt 0x20c: proc: Submit Request Answer 0x20c: 30f30a00000000000000 | irmovq $10,%rbx…
