9.2 Discuss the hardware support required to support demand paging. Answer: For every memory access operation, the page table needs to be consulted to check whether the corresponding page is resident or not and whether the program has read or write privileges for accessing the page. These checks would have to be performed in hardware.

Demand Paging Hardware Support. Hardware support to demand paging. Page Table: Table has the ability to mark an entry invalid through a valid-invalid bit/special value of protection bits. Secondary Memory: Holds pages that are not in main memory (disk), known as swap device and section of disk used for this purpose is swap space/backing store.

In computer operating systems, demand paging (as opposed to anticipatory paging) is a method of virtual memory management. In a system that uses demand paging, the operating system copies a disk page into physical memory only if an attempt is made to access it and that page is not already in memory (i.e., if a page fault occurs).

Paging schemes, such as pure demand paging, result in large amounts of initial page faults as the process is started. Prepaging is an attempt to prevent this high level of initial paging by bringing into memory, at one time, all of the pages that will be needed by the process.

Hardware Support. So far, we have only mentioned that hardware works with the operating system to implement virtual memory. However we have glossed over the details of exactly how this happens. Virtual memory is necessarily quite dependent on the hardware architecture, and each architecture has its own subtleties. However, there are are a few ...
