> 中文摘要: 以降低分布式嵌入式系统整体能耗为目标,立足设备属性及其关系,从系统的启动设备集和设备动态供电电压两个方面着手,提出一种基于Agent的自适应能耗管理及其分析方法.在此基础上,给出分布式嵌入式能耗网(DE-Net),并利用DE-Net模型对系统的基本组件进行建模,根据组件间关系形成能耗模型,以刻画系统的执行流程和能耗属性.最后,利用CTL描述系统性质,并借助Petri网的操作语义来验证方法的正确性和有效性.具体实例应用及实验结果表明:该方法能够有效地降低分布式实时系统的能耗,正确描述能耗自适应调整过程,简化建模和分析过程,对开发具有低能耗DES具有重要的理论意义和实用价值.
Abstract:In order to reduce the overall energy consumption of the distributed embedded system(DES), this paper proposes an adaptive energy management and analysis method based on the attributes of devices and their relationships by considering the boot device set and the dynamic supply voltage of devices. The study results in the distributed embedded energy consumption net (DE-Net) which is used to model the basic components of the embedded system. The model of energy consumption is then formed to characterize the execution process and the attributes of energy consumption. Finally, CTL is used to express the basic properties of DES. The operational semantics of Petri nets helps verify the correctness and effectiveness of the proposed method. The example and experimental results show that this method can correctly describe the adaptive energy consumption of DES and simplify the modeling and analysis process, which has important theoretical significance and practical value for developing the low energy consumption of DES.
