Noncontiguous Logical Address Spaces
- Varying the size of the segments can lead to misuse of the segment sizes, assuming that the number of segments is limited.
- Why not just fix the size of the segments? Then, we can eliminate the “bound” column in the segment table and agree that all segments are of an equal, fixed size. We’ll call these new fixed-size segments pages.
- Page Table Entry - Pointer to physical memory frame.
- Page table - collection of page table entries.
- Again we divide the logical address into separate portions (4-bit page and 12-bit offset) - Figure 11.8.
