CHALLENGE ACTIVITY 7.1.1: Virtual address translation. Jump to level 1 Assume a virtual memory system that uses demand paging. Whenever a PT or page is not resident in memory, the corresponding table entry contains a negative number. Segment table and page table entries contain frame numbers of the corresponding page tables or pages. Size of segment table = size of page table = size of page = size of frame = 512 words. Segment table (ST) starts at address 0 of physical memory. 3 Physical memory (PM) has the following contents: 5 0 1 2 3 1536 1537 1538 4 9 -6 2560 2561 -7 11 PM -1 5 3 -5 Complete the table and determine if the VA causes a page fault. Enter "N/A" if frame number is unknown. VA = (s, p, w) Frame number of PT Frame number of page Page fault? 1 (2, 1,6) Ex: 1 or N/A Ex: 1 or N/A Pick 2 (3,7,0) Pick 3 (1,0,20) Pick 4 (1,1,14) Pick ACTIVITY 7.2.1. databases.
