摘　　要：新一代嵌入应用需要自配置和定制操作系统,剪裁掉不必要的系统功能来获得更高的性能和更低的系统开销。软件构件是以可重用为目的设计、封装软件的技术,是操作系统配置管理的基础。提出设计构件化可配置实时嵌入式操作系统的方法:系统功能划分、构件界面划分、配置处理,并依据该理论进行了系统设计与实现,原型系统证明是可配置的,易于用户定制的,也提供了实时嵌入式操作系统所必要的特性。New embedded applications need self-configure and customized operating systems,to meet the requirement of specific application and different applying fields. By cutting off the unnecessary parts of the system, it reaches high- er performance and requires low consumption of the system. Software component technology is a technique for de- signing and encapsulating aimed at reuse. It is the foundation of the configuration and management of an operating system. Suppose the design method of the componentized configurable real-time embedded operating system based on the study of contemporary real-time embedded operating system and component technology: defining system function, defining interface, configuration process. It also includes the devise of the configurable real-time embedded operating system. The prototype system is proven to be configured and easy to be customized. Last but not least,it provides the obligatory characteristics of the real-time embedded operating system.
