嵌入式实时操作系统μC/OS-II与eCos的比较

在嵌入式应用系统中使用嵌入式操作系统可以提高应用系统的开发效率和提升嵌入式应用系统的稳定可靠性，因此，在嵌入式应用系统中使用嵌入式操作系统将成为嵌入式应用系统的设计主流。

本文将介绍嵌入式实时操作系统μC/OS-II在ARM上的移植

在嵌入式实时操作系统中,如何在操作系统层面尽量降低系统功耗已成为一个值得研究的问题。本文以嵌入式实时操作系统μC/OSII为例,以飞思卡尔8位单片机HCS08GT60作为硬件平台,详细讨论如何实现一个低功耗的实时操作系统,如何利用μC/OSII内核扩展接口省电;详细分析如何选择一种合适的单片机低功耗模式,说明利用μC/OSII内核扩展接口实现一个低功耗系统的可行性。

近些年来，数字化技术高速发展，嵌入式产品已经出现在我们生活中的方方面面。嵌入式操作系统又作为嵌入产品的基石，在产业发展过程中扮演了越来越不可替代的角色。本文主要研究了嵌入式操作系统中应用较为广泛的、源代码开放的μC/OS-II在STM32芯片上的移植。

通过一个具体的实例——电脑自动打铃器来阐述嵌入式应用系统的工程设计方法。

可以快速查询μC/OS-II中的功能函数的产地参数，用法，及注意事项，很全面，所有函数按照字母排序

This book describes the design and implementation of mC/OS-II (pronounced "Micro C O S 2") which stands forMicro-Controller Operating System Version 2. μC/OS -II is based on μC/OS, The Real-Time Kernel which was firstpublished in 1992. Thousands of people around the world are using μC/OS in all kinds of applications such ascameras, medical instruments, musical instruments, engine controls, network adapters, highway telephone call boxes,ATM machines, industrial robots, and many more. Nu merous colleges and Universities have also used μC/OS toteach students about real-time systems.μC/OS-II is upward compatible with μC/OS (V1.11) but provides many improvements over μC/OS such as theaddition of a fixed-sized memory manager, user definable callouts on task creation, task deletion, task switch andsystem tick, supports TCB extensions, stack checking and, much more. I also added comments to just about everyfunction and I made μC/OS -II much easier to port to different processors. The source code in μC/OS was found in twosource files. Because μC/OS-II contains many new features and functions, I decided to split μC/OS-II in a few sourcefiles to make the code easier to maintain.If you currently have an application (i.e. product) that runs with μC/OS, your application should be able to run,virtually unchanged, with μC/OS-II. All of the services (i.e. function calls) provided by μC/OS have been preserved.You may, however, have to change include files and product build files to ‘point’ to the new file names.This book contains ALL the source code for μC/OS-II and a port for the Intel 80x86 processor running in Real-Modeand for the Large Model. The code was developed on a PC running the Microsoft Windows 95 operating system.Examples run in a DOS compatible box under the Windows 95 environment. Development was done using theBorland International C/C++ compiler version 3.1. Although μC/OS-II was developed and tested on a PC, mC/OS-IIwas actually targeted for embedded systems and can easily be ported to many different processor architectures.

前段时间我阅读了杨屹的关于“ ucos51 移植心得”，并考虑到能否将ucos-II 移植到KeilC51 的小模式下。由于小模式运行速度比大模式运行速度快很多，这将有利于提高系统 的速度。 2
