Abstract

Power and energy consumption have become important for all computers, but the tools used to measure and optimize power on physical hardware lag far behind performance focused tools. Existing measurement apparata have low analog bandwidth, do not explicitly correlate power data with processor activity, and are not explained in sufficient detail to quantify uncertainty in their data. We present the design, implementation, and application of Jouler’s Loupe, a measurement device that overcomes these obstacles and enables a new generation of fast, fundamentally sound energy-efficiency-focused tools. We demonstrate substantial opportunity for energy-focused software optimizations on a mobile CPU core.
