Abstract

Disclosed is a method for processing a page fault by a processor. The method includes performing demand paging depending on an application operation in a system including a processor and an operating system, and loading, at the processor, data on a memory in response to the demand paging.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2020-0065330 filed with the Korean Intellectual Property Office on May 29, 2020, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] Embodiments of the inventive concepts described herein relate to a method for handling page faults by a processor. Background technique [0003] Nowadays, in a computer system environment using a page-based virtual memory technology, a demand paging technology is widely used to efficiently use memory. In conventional demand paging techniques, a demand page is generated based on the content of a page table entry corresponding to the virtual address to which the demand page is to be applied. [0004] Meanwhile, additional information (eg, swap offset) may be stored in the free bit space of the page table entry, if necessary. In this case, a processor (eg, a central processing unit (CPU)) may not be able to resolve the a...
