1. Address Layouts Our OS uses 32-bit virtual addresses, 24-bit physical addresses, and page sizes of 4KB.
Draw the layout of both the virtual and physical addresses along with the size in bits.
Please just do the drawing, that's all that is needed

1. Assume that your machine uses 16-bit virtual address and 14-bit physical address with 4KB page size. To get full credit, show your work. a. Show bits of the virtual address and physical address. b. What is the maximum program size that can be run in this machine? c. What is the maximum physical memory that this machine can have? d. Show the numbers of virtual pages and page frames. e. What is the table size if a page entry...
The RISC-V 32-bit architecture supports virtual memory with 32-bit virtual addresses mapping to 32-bit physical addresses. The page size is 4Kbytes, and page table entries (PTEs) are 4 bytes each. Translation is performed using a 2-level page table structure. Bits 31:22 of a virtual address index the first-level page table. If the selected first-level PTE is valid, it points to a second-level page table. Bits 21:12 of the virtual address then index that second-level page table. If the selected second-level...
Assume you have: 32-bit addresses, 4KB Page size, 4MB Physical Memory Space, 4KB Cache with 4-way set associative and LRU replacement, 32 Byte Cache block size, 4-entry fully associative TLB. A program to be run on this machine begins as follows: double A[1024]; int i, j; double sum = 0; for( i = 0; i < 1024; i++ ) // first loop A[i] = i; for( j = 0; j < 1024; j += 16 ) // second loop ...
Consider a virtual memory system with the following properties: 36 bit virtual byte address, 8 KB pages size, and 32 bit physical byte address. Please explain how you determined your answer. a. What is the size of main memory for this system if all addressable frames are used? b. What is the total size of the page table for each process on this processor, assuming that the valid, protection, dirty, and use bits take a total of 4 bits and...
1) Given a virtual memory system with: virtual address 36 bits physical address 32 bits 32KB pages (15 bit page offset) Each page table entry has bits for valid, execute, read and dirty (4 bits total) and bits for a physical page number. a) How many bits in the page table? (do not answer in bytes!) Three digit accuracy is good enough. The exponent may be either a power of 2 or a power of 10. b) The virtual address...
page addressing (a) The following are virtual 16 Considered bit-addresses, with the upper 8th Bit the number of the page and the lower one 8th Bit represent the offset. The physical memory included in this example 256 Page frames ( frames ) to each 256 Bytes per page, ie physical addresses from 0x0000 to 0xFFFF, where frame 0 at 0x0000 starts. Given the following page table for a process that 10 Pages (page numbers 0 - 9), some of which...

Suppose that we have a computer system using 32-bit logical address and 46–bit physical address. It also uses paging for memory management with a single-level page table organization. The page size is 4K bytes and each page table entry is 32 bits or 4 bytes in size. Calculate the number of bits in each field in the logical address, the size in bytes of the page table, and the number of frames.
Please use the python to write Assume that a system has a 32-bit virtual address with a 4-KB page size. Write a program that is passed a virtual address (in decimal) on the command line and have it output the page number and offset for the given address. As an example, your program would run as follows: ./addresses 19986 Your program would output: The address 19986 contains: page number = 4 offset = 3602 Writing this program will require using...
A computer has 32-bit virtual addresses and the page size is 2^3 KB. Suppose the text, data, and stack segments of a process need 5 page(s) each. If the computer uses two-level page tables, with 3 bits for the second-level index, how many page table entries (PTEs) are in each second-level page table?
