嵌入式软件体系结构级能耗建模方法

摘要

从软件体系结构层面出发,假设体系结构级软件特征量与嵌入式软件能耗之间存在非线性函数关系(线性函数关系可被认为是一种特殊的非线性函数关系),并以此假设为基础,提出了一种利用BP神经网络在体系结构级估算软件能耗的模型,能耗模型对5个体系结构级软件特征量进行度量,使用BP神经网络拟合出软件特征量与嵌入式软件能耗的非线性函数关系,并通过实验验证了模型的有效性和假设的合理性.%This paper starts at a software architecture level, considers the functional relation between software characteristic quantities and embedded software energy as nonlinear (linear functional relation can be considered as a special nonlinear functional relation). Next, the paper presents an energy model at architecture level by using BP neural network. The energy model measures S software characteristic quantities at architecture level and uses BP neural network to fit the functional relation between software characteristic quantities and embedded software energy. Experimental results show that this model is effective.
