Memory Management Virtual Memory – Page Replacement Algorithms » The Second-Chance Page Replacement Algorithm similar to the FIFO algorithm but check the Referenced bit REPEAT – dequeue the page – if the Referenced bit is set, clear the Referenced bit, and enqueue it – if the Reference bit is not set, remove the page UNTIL a page with a clear Referenced bit is dequeued Guaranteed to terminate. Why? Copyright © 2007 David Vernon (www.vernon.eu)
Memory Management Virtual Memory – Page Replacement Algorithms » The Clock Page Replacement Algorithm similar to the Second Chance algorithm except use a circular queue and, instead of dequeueing and enqueueing, move the queue head pointer Copyright © 2007 David Vernon (www.vernon.eu)
