摘要
在SoC系统中,嵌入式CPU内部的复杂性和应用需求使得其指令级功耗建模十分困难,为此提出了一种基于数据流的指令级功耗建模方法,考虑到了CPU内部信号变化对功耗的影响。采用包括了所有指令类型的7个算法程序作为样本的验证结果显示该模型具有较快的执行速度和稳定的计算精度,可以为低功耗EDA软件设计提供指导。
The verification and estimation for power consumption in embedded microprocessor of SoC is very difficult due to the complexity of CPU itself and the application demand, so the instruction-level power consumption modeling method is put forward based on the dataflow, which takes the power consumption produced by the internal signal changes into consideration. The results of the test using seven arithmetic procedures including all instruction types show that the model has a faster speed and stable calculation accuracy, and can offer guidance for low-power EDA software design.
