Full system simulation tool released for intermittent computing systems

We have recently released Fused, a tool developed by Arm-ECS PhD researcher Sivert Sliper for full system simulation of energy-driven and intermittent computing systems. 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 this way, we can model an embedded system through power cycles.
