摘要：Energy conservation is a critical issue in battery operated systems. Energy consumption reduction of portable embeddedsystems is essential for increasing the battery life, enabling better system usefulness. One of the promising techniques ofenergy consumption reduction is Dynamic Voltage and Frequency (DVFS). In this paper, a Dynamic Frequency Scaling(DFS) method is used to reduce the energy consumed by an Atmel ATmega 16 microcontroller while executing a roboticapplication. A noticeable amount of energy saving was observed both by simulation and experimental validation whenswitching frequency was varied from rated frequency to below rated frequencies, without violating any of the temporalrequirements.
