摘要: 为简化应用程序的编写,在嵌入式系统开发时,采用实时嵌入式操作系统开发平台,将源码开放的嵌入式实时操作系统Toppers/asp内核,移植到嵌入式微控制器ARM7(S3C44B0)。该方法能解决系统启动和加载过程中的特定工作状态等问题,明确Toppers/asp内核在移植过程中的重点和难点。经多任务运行结果表明,Toppers嵌入式实时操作系统稳定可靠。

关键词: 实时操作系统, Toppers内核, ARM处理器, 任务切换

Abstract: In order to simplify the application program, the Real Time Operating System(RTOS) is utilized in the embedded system development. This paper proposes the method of porting open source RTOS Toppers/asp onto ARM7(S3C44B0), which is a popular microcontroller dedicated to embedded system. It solves the key problems in the startup and loading of system, and presents the most important and difficult problems in the course of porting Toppers/asp. Multitask running result shows that the system is steady and reliable.

Key words: Real Time Operating System(RTOS), toppers kernel, ARM processor, task switching
