In this work, we provide an experimental comparison between Global-EDF and Partitioned-EDF, considering the run-time overhead of a real-time operating system (RTOS). Recent works have confirmed that OS implementation aspects, such as the choice of scheduling data structures and interrupt handling mechanisms, impact real-time schedulability as much as scheduling theoretic aspects. However, these studies...
This paper addresses an approach for accurately measuring energy consumption on battery-powered embedded systems which can be adequately tuned in order to enhance a set of timing and energy consumption metrics for mission critical systems. We introduce a software-based accounting scheme which is calibrated by low-precision battery state-of-charge reads through a battery voltage model. We then perform...
