Being able to accurately estimate CPU power consumption is a key requirement for both controlling online CPU energy-saving techniques and design-space exploration. Models built and validated using measured data from an actual device are extremely valuable as their accuracy is known and trusted. PowMon produces power models that are both accurate and stable. The open source PowMon software tools consists of a number of distinct parts: Software tools which allow researchers to implement our automated model building methodology, and produce power models of a platform that are both accurate and stable. Downloadable power models for existing mobile CPUs (quad-core Cortex-A7 and quad-core…
