Fused: Full-System Simulation of Energy-Driven Computers

Fused is a full-system simulator for modelling energy-driven computers. To accurately model the interplay between energy-availability, power consumption, and execution; Fused models energy and execution in a closed feedback loop. The power model is based on recording high-level events (memory accesses, peripheral operations etc.) and states (modules on/off, peripheral operation modes etc.), and computing the instantaneous power consumption at runtime. Simultaneously, external circuitry such as e.g. energy storage, power supply and power management is modelled. The power consumption, power supply, and energy-availability, is then used to calculate the supply voltage, which in turn is monitored by the modeled microcontroller. In…

PowMon: Accurate and Stable CPU Power Estimation

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…
