Two level page table
WebHierarchical Paging is one of the simplest techniques and for this purpose, a two-level page table and three-level page table can be used. Two Level Page Table. Consider a system … WebFor virtual address 60000: (1) 4-KB page: 60000/4096=14, remainder 2656. Virtual page number is 14, offset is 2656. (2) 8-KB page: 60000/8192=7, remainder 2656. Virtual page number is 7, offset is 2656. (5 points) Given a two-level page table with 4-KB pages and. Assume that each level uses 10 bits. What would be the virtual address if PT1=2 ...

WebIn our example, this table must contain 2^10 entries (one for each POPT), each of which is 4 bytes (it contains a 20 bit frame pointer and additional VDRWX bits). Thus the total size of the top-level page table is 2^10 entries * 2^2 bytes per entry = 2^12 bytes = 4kb. This fits in one page, so there is no reason to split it further. WebA three-level table? I believe the answer is still 1. Once the hardware has indexed into the first page-table it obtains the address of the next page-table (assuming the first is a valid entry). Requiring a register for each possible page table in a 32-bit virtual address space would be impractical. Use the simulator to perform translations ...
