Research and Implementation of Operating System With Basic Functions Based on IA32
Abstract：Operating system is the most basic part of computer software, it is the core software of computer. And it is a professional core course in Computer Science. It is highly theoretical and its concepts are too abstract to understand. It involves not only computer software but also some hardware knowledge. Generally speaking, it is a big challenge for beginners. This project introduces a implementation of the basic functions of operating system by standing in the learners’ angle. This project includes implementation processes of the boot sector, interrupt processing, graphical interface, multi task and the command line. During this paper, it also introduces the relevant theoretical knowledge of each part. It aims to provide a bridge from theory to practice for beginners. With this project, people can deeply understand the theory and be more familiar with the operation of operating system.
Key words: operating system; protected mode; interrupt handling; memory management.
