- Determine the number of page table entries (PTEs) that areneeded for the following combinations of virtual address size(n) and page size (P):On a simple paging system with 224 bytes of physical memory, 256 pages of logical address space, and a page size of 210 bytes. 1. How many bits are needed to store an entry in the page table (how wide is the page table)? Assume a valid/invalid 1-bit is included in each entry. 2. If the page table is stored in the main memory with 250nsec access time, how long does a paged memory reference take? 3. If the page table is implemented using associative registers that takes 95nsec. and main memory that takes 200nsec, what is the total access time if 75% of all memory references find their entries in the associative registers?If logical address is (0001100001011) binary find page number p: displacement d: suppose the page addressed above is stored at frame 7. the physical address for the word addressed above is physical address: please show and explain all steps
- Take a look at a 64-bit logical address space. a. Assuming a page size of 4 KB Discover the truth. How many page table entries are there? Answer. b. Determine if each entry is 16 bytes long. Page Table Dimensions Answer.Mapping from high level addresses to low level addresses is known as address resolution. True or False?Assume a 32-bit address system that uses a paged virtual memory, with a page size of 2 KB, and a PTE (Page Table Entry) size of 1 B. Answer the following questions, assuming a virtual address 0x00030f40 a. What is the virtual page number (VPN) and the offset in binary for the given virtual address? b. How many virtual pages are there in the system?
- For each of the following decimal virtual address : 32768, 60000. Compute the virtual page number and offset for 8KB page.Suppose we have a byte-addressable computer using direct mapping with 16-bit main memory addresses and 32 blocks of cache. If each block contains 8 bytes. a. Determine the number of bits of the tag field. b. To which cache block would the hexadecimal address 0x2468 map? c. What is the tag of the hexadecimal address 0x2468A machine has 48-bit virtual addresses and 32-bit physical addresses. Pages are 8 KB. How many entries are needed for a single-level linear page table?
- Assuming a 16 KB page size, what are the page numbers and offsets for the following address references (provided as decimal numbers): Show calculation steps 7632 26963 10810Assume a 32-bit address system that uses a paged virtual memory, with a page size of 2 KB. Answer the following questions, assuming a virtual address 0x00030f40 A. What is the virtual page number (VPN) and the offset in binary for the given virtual address? B. How many virtual pages are there in the system?Given a 32-bit virtual address space and a 24-bit physical address, determine the number of bits in the VPN, VPO, PPN, and PPO for the following page sizes P. Drag the appropriate labels to their respective targets.
