Abstract: Along with the quick development in every fields of embedded system, the porting technology of embedded operating system has become an important problem of embedded development. This paper investigates the theory and technology of porting embedded operating system to different hardware flats, and advances a scheme which can be used to port embedded operating system with the means of blocking and layered. This scheme is applied to the project of porting CRTOSII to the board which integrates the chip of S3C2410. It proves the validity and feasibility of the scheme.

Key words: realtime operating system(RTOS), CRTOS II, hardware interrelated layer, layered, blocking

摘要： 随着嵌入式系统在各个领域的不断发展，嵌入式操作系统的系统软件移植技术的研究已成为嵌入式开发中的一个重要问题。该文研究了嵌入式操作系统在不同平台移植的理论与技术，提出一种用层次化和模块化方法对嵌入式操作系统进行移植的一般方案。该方案成功运用于CRTOSII移植到集成S3C2410芯片主板的项目中，实践证明了移植方案的正确性和可行性。
