摘　　要：伴随着AI、边缘计算、物联网等技术的发展,软件的复杂度和功耗与日俱增。人们对于嵌入式软件功耗的关注也不断提高。在前人的基础上,提出了一种软件功耗仿真度量、建模与优化的通用设计框架。从系统的层面,将软件功耗的仿真度量、建模优化分成了硬件仿真、指令级测量分析、软件功耗建模和功耗分析与优化4个层级。并根据此分层结构实现了HMSimV4.0。HMSimV4.0的实验结果表明,该方法构造的HMSimV4.0能够有效完成软件功耗的仿真度量、建模与优化任务。Abstrac:With the development of AI,edge computing and Io T,the complexity and energy of software are increasing quickly.People’s attention to software power energy is also increasing.Based on the predecessors,this paper proposes a general design framework for software energy simulation measurement,modeling,and optimization analysis.From the system level,the software energy simulation measurement and modeling optimization are divided into four levels:hardware simulation,instruction-level measurement analysis,software energy modeling,and the energy analysis and optimization.Based on this layered structure,HMSimv4.0 was realized.The experimental results of HMSim V4.0 show that HMSim V4.0 constructed by this method can effectively complete the tasks of simulation measurement,modeling and optimization analysis of software energy.
