多網卡省電封包收集策略

Abstract

近幾年來,越來越多的多核心架構被提出來並且漸漸流行。而這些 架構都是為了裝電池的移動型設備。 對於這種設備來說,儘可能延長 設備的不插電使用時間使很重要的。本論文在設備的部份提出一種多 設備互相合作的一種排程方法來達到省電。在中央處理器的部份提出 一種預留處理器使用率的排程方法來省電,分別在設備方面使用動態 功率管理,中央處理器方面使用動態電壓頻率調整來處理。用模擬的 方式來驗證論文中提出的方法及得知省電的比例

In recent years, various multi-core architectures have become popular se- lections for the designs of battery-aware devices. It is important that devices have long operating time. In this paper, a cooperating-based approach is pro- posed to deal with device part scheduling and a reserving-based method is proposed to cope with processing unit part scheduling. DPM(Dynamic Power Management) is used on device part and DVFS(Dynamic Voltage Frequency Scaling) is used on processing unit part. The power saving ratio is evaluated by a series of simulation.
