摘要： 目前已存在的嵌入式操作系统要么是一个商业化的系统，昂贵的版权费用限制了它的使用；要么是一体化的内核结构，针对具体硬件平台定制移植困难。该文将构件化的软件设计方法引入到嵌入式操作系统的开发中，设计了一个可配置、可移植、能灵活扩展的嵌入式操作系统开发平台。基于此平台，可以针对不同的硬件体系结构、不同的应用迅速搭建嵌入式操作系统，不仅能够有效地减少开发的工作量，同时也缩短了开发时间、降低了成本。

Abstract: An existing embedded operating system almost has the following weakness: a commercial production or monolithic kernel architecture.The large payment of copyright limits the use of commercial EOS, and it's difficult to port a monolithic kernel EOS to a given hard platform.Therefore, component software technology is used to study and develop embedded operating system, and a configurable, portable, extendableembedded operating system is proposed and designed.

Key words: Embedded operating system; Component; Hardware abstraction layer; Microkernel
