Setting Up Paging: Difference between revisions

This is a guide to setting up paging. It will teach you the basic concepts behind paging and how it can help you with your OS. This example will concentrate on Legacy Non-PSE Non-PAE paging. Paging normally should not be the first part of your memory manager that you write. It is generally considered a good idea to first write a Page Frame Allocator (see [[Page_Frame_Allocation]]) that will manage the computer's physical memory for you. You can then design your paging system to not have to manage the physical memory on which it sits.

Paging allows you to have more than one virtual address space mapped into the realphysical address space. The [[MMU]] uses what is called a Page Directory to map virtual addresses to physical addresses.
