We consider a program that has two segments that are shown in the below table: Segment 0, containing instructions, and segment 1, containing data. The memory is a virtual memory system with:
- virtual addresses that have a 4-bit page number,
- and a 10-bit offset.
The page table entries are given as follows:
Segment 0 | Segment 1 | ||
Virtual Page # | Page Frame # | Virtual Page # | Page Frame # |
0 | 2 | 0 | On Disk |
1 | On Disk | 1 | 14 |
2 | 11 | 2 | 9 |
3 | 5 | 3 | 6 |
4 | On Disk | 4 | On Disk |
5 | On Disk | 5 | 13 |
6 | 4 | 6 | 8 |
7 | 3 | 7 | 12 |
For each of the following cases, either give the real (actual, physical ) memory address which results from dynamic address translation or identify the page fault.
a) Fetch from segment 1, page 1, offset 3
b) Store into segment 0, page 0, offset 16
c) Fetch from segment 1, page 4, offset 28
d) Jump to location in segment 1, page 3, offset 32
