摘 要
随着计算机和电子技术的发展,越来越多的嵌入式产品出现在人们的日常生活和工业生产之中。由于嵌入式
设备的智能型,使得生活和生产变得极为方便,由此也带来了嵌入式操作系统的迅速发展。μC/OS-Ⅱ内核作为一
种代码公开的嵌入式实时操作系统,ARM9以内核耗电少,成本低,二者相互搭配,构成了较为完美的搭配组合。
本文主要讲述的是μC/OS-Ⅱ在ARM9上的系统移植问题。
关键词:μC/OS-Ⅱ;Arm9;移植
Abstract
大庆师范学院本科毕业论文(设计)
With the development of computer and electronic technology, embedded has become an indispensable part of
modern society. Big to industrial production, such as aerospace, small to daily life, such as smart card applications,
many devices are built into the embedded, makes the equipment or device has a high automation performance and some
degree of intelligence, great convenience to people's production and living needs, and thus also brought the rapid
development of the embedded operating system. Mu C/OS - Ⅱ kernel code, as a kind of open embedded real-time
operating system, the ARM kernel, less consumption, lower cost, the two match each other, form the relatively perfect
collocation. This article mainly tells the mu C/OS - Ⅱ portability issues on the ARM of the system.
Keywords: u C/OS - Ⅱ; Arm; transplant
