<p><b>Abstract</b>—Many embedded systems operate under severe power and energy constraints. Voltage clock scaling is one mechanism by which energy consumption may be reduced: It is based on the fact that power consumption is a quadratic function of the voltage, while the speed is a linear function. In this paper, we show how voltage scaling can be scheduled to reduce energy usage while still meeting real-time deadlines.</p>
