This work presents an early stage statement-level metric for energy characterization of embedded processors. Definition and the framework for metric evaluation are provided. In particular, such a metric is based on an existing assembly-level analysis and some profiling activities performed on a given C benchmark, and it is related to the average energy consumption of a generic C statement, for a given target processor. Its evaluation is performed with a one-time effort and, once available, it can be used to rapidly estimate the energy consumption of a given C function for all the considered processors. Two reference embedded processors are then considered in order to show an example of usage of the proposed metric and framework.

这项工作提出了用于嵌入式处理器能量表征的早期语句级度量。提供了度量评估的定义和框架。特别是，这种度量基于现有的程序集级分析和在给定的C基准上执行的某些性能分析活动，并且与给定的目标处理器的通用C语句的平均能耗有关。它的评估是一次性完成的，一旦可用，就可以用来快速估计所有考虑的处理器的给定C函数的能耗。然后考虑两个参考嵌入式处理器，以显示所提出的度量和框架的用法示例。
