嵌入式应用中运行支撑框架的构件化技术研究

Research on Component-Based Runtime-Supporting Framework of Embedded Systems

为增强嵌入式软件的复用性、可移植性,缩短开发周期,通过研究现有的主流构件运行支撑技术,提出了一种面向嵌入式领域的运行支撑体系结构。为实现灵活、开放的嵌入式应用平台,本文首先建立了构件化的嵌入式运行支撑框架模型,然后结合PDA手机领域重点分析了开放式HLA结构和虚拟OS平台等关键技术,最后利用伪代码示例探讨了该领域中应用平台的定制与扩展方法。

To enhance the embedded software reuse and portability, shorten the developing cycle, based on a research for some main popular component-based runtime-supporting techniques, brought forward a kind of runtime-supporting frameworks for embedded systems. In this paper, to realize a flexible and open embedded application platform, a com- ponent-based runtime-supporting framework model is firstly constructed. Then, some critical techniques, such as an open HLA infrastructure and a virtual OS platform, are analyzed for the PDA software application platforms. Finally, some methods of customizing and extending those platforms are discussed in the form of pseudo code.
