是否可以在程序中提取指令的特定能耗?

问题描述

我的意思是，给定一个源代码文件，是否可以使用诸如perf之类的工具来提取特定代码块或1条单指令的能耗水平?

What i mean is that given a source code file is it possible to extract energy consumption levels for a particular code block or 1 single instruction, using a tool like perf?

推荐答案

使用 jRAPL 一个用于概要分析运行在CPU上的Java程序的框架.

Use jRAPL which is a framework for profiling Java programs running on CPUs.

例如，以下代码段尝试测量任何代码块的能耗，这些代码块的值是开始和结束之间的差值:

For example, the following code snippet attempts to measure the energy consumption of any code block, whose value is the difference between beginning and end:

double beginning = EnergyCheck.statCheck();
doWork();
double end = EnergyCheck.statCheck();
System.out.println(end - beginning);
