Techniques to Reduce
the Number of Page Faults
-
Make pages large enough to take advantage of spatial locality.
-
A virtual page can be placed anywhere in main memory (i.e. main memory
is fully associative).
-
The OS uses reference bits to approximate LRU when choosing which page
to replace.
-
Only write-back is used, so pages are only written back when they are
replaced and are dirty.
