基于任务间通信的嵌入式组件模型

通用组件技术如COM、CORBA等技术已较完善，但是它们应用于嵌入式系统却有很多局限，如需要庞大的底层基础支持、没有实时调度能力等。根据嵌入式系统以及应用的特点，分析了现有的通用组件模型和当前嵌入式组件技术的发展现状，提出了一种新的嵌入式组件模型——基于任务间通信的嵌入式组件模型。该模型具有资源消耗小、有实时调度能力、无须大量底层支持的优点，该文介绍了系统框架和实现方法以及组件开发方法。

Embedded Component Model Based on Intertask Communication

The common component technologies, such as COM, CORBA etc.. have been perfect, but there is some limit when they are plied to embedded systems. On the basis of embedded systems characteristics, this paper analyzes the present common component model and the characteristics of embedded component technologies, presents a new embedded component model, embedded component model based on intertask communication. The model has the advantages such as support for real-time scheduling, demanding less underlying technologies support and consuming less resource. This paper provides the explaining of system framework, implementation method and the method of developing component.
