安卓智慧型手機上的一個可感知服務品質排程方法

Abstract

大量現代移動應用程序需要高幀率的 UI 渲染，尤其是遊戲或基於 Web 的滾動多媒體視圖。 此外，Android平台運行的前提是空閒內存是浪費內存，所以它總是試圖使用所有可用內存，從而增加內存壓力。 在本文中，我們觀察到當系統內存壓力較高時會出現 QoS 問題。 通過對 UI 渲染的案例研究，我們提出了一個可感知QoS 的調度方法，以滿足高幀率性能和最小的功耗。 實驗結果表明，所提出的解決方案能夠有效地解決 QoS 問題，性能提高了 55%，而功耗僅增加了 11%。

A vast amount of modern mobile applications demand high frame rate on UI rendering, especially games or scrolling web-based multimedia views. Moreover, the Android platform runs on the premise that free memory is wasted memory so it tries to use all of the available memory at all times hence enhancing the memory pressure. In this article, we observe that QoS problem occurs when system memory pressure is high. By a case study on UI rendering, we proposed a QoS-aware scheduling scheme to satisfy the high frame rate performance with minimized power consumption. The experimental results showed that the proposed solution is able to solve the QoS problem efficiently by improving up to 55\% performance while merely increasing 11\% power consumption.
