A Virtual Address Has The Form S1 S2 P W Where Each Component Is 2 Bits The Page Table Of The Paged Segment Table 1 (288.14 KiB) Viewed 34 times

- A virtual address has the form (s1,s2,p,w) where each component is 2 bits. - The page table of the paged segment table starts at address 32. - A dash denotes a nonexistent page or page table. - A positive number, n, in a table means that the page currently resident in memory staring at address n. - A negative number, −n, in a table means that the page is not resident in memory and must be loaded from the disk. The value of n then gives the disk block containing the missing page. Ex: A -2 in a page table entry indicates that the page is not in main memory and can be found in disk block 2. (a) Starting with the page table of the segment table at address 32, trace down the entire memory hierarchy and label each frame as: "page p of the segment table," "page table of segment s," or "page p of segment s," where p and s are the actual page and segment numbers. Page frames that remain unmarked are free. (b) Translate virtual address 113 into a physical address and determine the content. (c) Translate the virtual address 68 into a physical address and determine the content. Show all changes to the memory hierarchy as a result of the translation. (d) Show all changes to the memory hierarchy as a result of deleting segment 7 .
