摘要
当前嵌入式实时操作系统(RTOS)的使用使得实时应用程序的设计和扩展变得容易,不需大改动就可增加新的功能,对时间要求苛刻的事件能快捷、有效地处理。通过有效的系统服务,RTOS使得资源得到更好利用。μC/OS-Ⅱ是一个基于优先级的抢占式实时内核的实时操作系统,程序可读性强,移植性好,代码固定,可裁剪,非常灵活,源码公开,所以得到了广泛应用。介绍了μC/OS-Ⅱ内核的特点、工作原理;通过实验将其在ARM处理器上移植,证明了其较好的移植性。
Currently, it makes design and extension of the real time application easy that the embedded real time operating system （RTOS） is applied. RTOS can add new function when it needn＇t be changed more,and it can deal with the real time case effectively. Via effective system serve,RTOS makes use of resource.μC/OS-Ⅱ is a real time operating system based on PRI,oecupied and real time kernel. Programme has stronger readability and better replanted nature. The code is fixed and it can be cutted out. So it has very good agility. This paper describes characteristic and work elements of μC/OS-Ⅱ kernel. At the same time, with experimentation, RTOS is replanted to the ARM processor. The experimentaion testifies its better replantated nature.
