Using paging as the core mechanism to support virtual memory can lead tohighperformanceoverheads. Bychoppingtheaddressspaceintosmall, fixedsized units (i.e., pages), paging requires a large amount of mapping information. Because that mapping information is generally stored in physical memory, paging[r]
Mỗi máy tính đều cần một bộ xử lý trung tâm để hoạt động, xử lý các chương trình vi tính và dữ kiện mà người dùng yêu cầu sau đó xuất ra những thông tin mà người dùng mong muốn, bộ phận đó thường được biết đến với tên gọi là CPU.

Professor: So, Student, did you learn anything? Student: Well, Professor, that seems like a loaded question. I think you only want me to say “yes.” Professor: That’s true. But it’s also still an honest question. Come on, give a professor a break, will you? Student: OK, OK. I think I did learn a few[r]
Before we end our study of virtual memory, let us take a closer look at one particularly clean and well done virtual memory manager, that found in the VAXVMS operating system LL82. In this note, we will discuss the system to illustrate how some of the concepts brought forth in earlier chapters toget[r]

Introduction Years ago, IBM sold expensive mainframes to large organizations, and a problem arose: what if the organization wanted to run different operating systems on the machine at the same time? Some applications had been developed on one OS, and some on others, and thus the problem. As a soluti[r]

In developing the virtualization of the CPU, we focused on a general mechanism known as limited direct execution (or LDE). The idea behind LDE is simple: for the most part, let the program run directly on the hardware; however, at certain key points in time (such as when a process issues a system ca[r]
