指導教授 : 郭大維

摘要


減少耗電是支援新興行動應用服務於下一代智慧終端主要的挑戰之一。相對於之前在動態電壓頻率調節排程演算法的研究及以歷史資料為基礎來做預測的技巧,這個研究的動機來自於行動應用程式在硬體資源上的使用模式之觀察,並提出資源驅動式動態電壓頻率調節方案,其中資源狀態機是被設計來模組化資源的使用模式並以在線的方式來操縱動態電壓頻率調節。我們在Android上實作了所提出的方案並且作了以真實應用程式為主的實驗。實驗的結果引領顯示了此方案的實用性及功效是令人鼓舞的。

並列摘要


Reducing the energy consumption is a major challenge in sustaining mobile applications and services for the emerging genre of smart handheld devices. In contrast to previous works on DVFS scheduling algorithms and history-based prediction techniques, this work is inspired by an observation on the usage patterns of mobile applications on hardware resources, and proposes a resource-driven DVFS scheme, where resource state machines are designed to model the resource usage patterns in an online fashion to guide DVFS. We have implemented the proposed scheme in Android and conduct experiments based on real-world applications. The results of experiments conducted to demonstrate its practicability and efficacy are very encouraging.
