Dynamic voltage and frequency scaling over delay constrained mobile multimedia service

This paper proposes an application of dynamic voltage and frequency scaling (DVFS) which is used in the power saving technique to process video decoding which requires much energy consumption in handheld devices having power limitations. The proposal of this paper is a DVFS application method to prevent an execution delay while applying DVFS and the complexity estimation method. The proposed method can achieve energy gains in power-limited and quality-sensitive video decoding settings by providing a computationally inexpensive power management technique.
