摘　　要：在分析ARM指令集的寻址方式、寄存器个数、指令周期数等特征的基础上,考虑三级流水线对指令集能耗特征的影响,提出一种层次分类能耗测量方法。实验结果验证了该方法的有效性,得出指令集能耗与电流值和指令周期数的乘积呈正比,减少指令周期数能降低指令集能耗,并且3种应用程序用例在仿真平台HMSim的测量值与W90P710实际目标板的能耗值相接近,绝对误差在10%以内。According to the analysis of addressing mode of ARM instructions,the number of registers,and the number of instructions cycles etc,this paper considers the influence of three-level pipelining to the energy and proposes a hierarchical classification energy consumption measurement method.Experimental result shows that this method can efficiently measure the power consumption of the instruction set,and concludes that the energy consumption of instruction set is nonnegative with the product of current and the instruction cycles.Reducing the cycles can reduce the energy of instruction set.The measured energy value of 3 kinds of program executed on HMSim simulator is close to the energy of executed on the target board W90P710,the absolute error is below 10%. ？
