Summary/Abstract: This paper utilizes energy models for embedded systems with variable execution speed. Energy models are combined with real-time computational models. Four computational models are in focus: single clock rate, two clock rates, single task loop and constant time for peripherals. A mathematical framework has been developed to calculate individual execution rates for each task. As a result, the framework is capable of providing seven optimal execution rates for the four computational models. In the rest five cases, the framework determines the best end point.
