“…Said approach also considers the effects of caches, cache misses, or stalls. In [10], a formal analysis for an 8-bit microcontroller has been proposed which also considers the power consumption of peripherals and not only the microcontroller itself. Both methods can reveal particularly power intensive software parts and estimate the rough overall power consumption.…”

To achieve a good estimate of the power consumption of an embedded system, including its firmware, is a crucial step in the development of systems with a severely constrained power supply. This is especially true for cases where the device is powered by a small battery or through energy harvesting. The state-of-the-art approaches to measure or estimate the power consumption are formal methods, using power debugging tools with the real hardware or simulation based estimations. In the work at hand, a novel method to estimate the power consumption is proposed, it utilizes the sensor-in-the-loop architecture and enhancing it with a power estimation functionality. The proposed method combines the benefits of former methods, allowing for run-time analysis of the power-consumption in a reproducible way using recorded data without the need for power debugging hardware. In the experiments it is shown that, once set up, the proposed method is able to estimate the power consumption with an error of less than 1 % compared to a power debugging hardware. Thus, the proposed method provides a reliable and fast way to estimate the systems power consumption.
