The serious issues are the way to execute LRU page replacement. An LRU page-replacement algorithm may need considerable hardware help. The issue is to decide on a request for the frames …

Witryna6 mar 2012 · This has the advantage of allowing you to replace the underlying concrete class with any class that provides the Queue interface, without having to change the code too much. The basic changes are to change the type of fifo to a Queue and to use remove() instead of removeFirst(), the latter being unavailable for the Queue interface. WitrynaFIFO Page Replacement Algorithm Start traversing the pages. Now declare the size w.r.t length of the Page. Check need of the replacement from the page to memory. …
