Paging Questions 1. A page is 1 KB in size. How many bits are required to store the page offset? 2. A page entry has 10 bits. What is the size of the page table? 3. A logical address is 32 bits long. The page size is 4 KB. Divide the address into its page number and offset. 4. The following hexadecimal addresses are used in a system with a 20-bit logical address where the page size is 256 bytes....
Suppose a memory manager employs paging with page size of 4 Kbytes. It has a memory of 256 Mbytes. A process of size 25 Kbytes needs to be loaded into memory. Answer the following. (a) How many frames are there in the memory? (b) How many bits are necessary to represent the physical address as <frame#, offset>? (c) How many frames need to be allocated to the process? Suppose a memory manager employs paging with page size of 4 Kbytes....
Problem #1 (25 points) Address Space, Memory Consider a hypothetical 18-bit processor called HYP18 with all registers, including PC and SP, being 18 bits long. The smallest addressable unit in memory is an 8-bit byte. A. (4 points) What is the size of HYP18's address space in bytes and KB? How many address lines does HYP18 require? Address space: Bytes Address space: KB (KiloBytes). Address bus lines: B. (6 points) Assume that first quarter of the address space is dedicated...
Assume that the following section of main memory is used to store the page table for 3 different processes. The page-table base register values for process P1 is 1080, for P2 is 1085, and for P3 is 1090. Assume that the contests of memory below correspond to frame numbers. Also assume that frame size is 4096 contents 3584720 15 11 18 6 20 24 910 13 30 38 40 1 addresses 0 0 0 0 0 O 000 0 00...

Virtual memory address translation: a) Consider a machine with a physical memory of 8 GB, a page size of 4 KB, and a page table entry size of 4 bytes. How many levels of page tables would be required to map a 52-bit virtual address space if every page table fits into a single page? b) Without a cache or TLB, how many memory operations are required to read or write a page in physical memory? c) How much physical...
