一种面向环境可配置嵌入式系统软件模型研究

Research of reconfigured embedded systems for environment

嵌入式系统硬件资源是相对固定且有限,为了适应环境,就需要系统从软/硬件上可重构。基于此,提出了一种基于可配置构件面向环境的嵌入式系统模型。它能适应不同环境下,面向任务地对系统进行重构来完成使命。通过可重构缩小了系统成品体积,节省了硬件资源,提高了系统可重用性。该模型在某航空机载设备中得到实际应用,解决了由来已久的问题,提高了系统的灵活性和自适应性。

In order to adapt variable environment, the system needs a dynamic mechanism to deal with it. For embedded systems, hardware is usually limited and fixed; for adapting environment, the system needs to be reconfigured from software to hardware. On the basis of reconfigured component, this paper proposed an embedded system model facing environment. The techniques could make the system adapt different environment and achieve mission through reconfiguration. By reconfiguration, it reduced finished product bulk, saved hardware. The model applied in some avionic device; it solved the long-standing problem and improved the system flexibility and adaption.
