摘要

行動系統將越來越多地展現出具有極高顯示分辨率和密度的新興 OLED 顯示器。在過去，大多數論文集中在分別降低了 GPU 功耗或省 電功耗。本文探討瞭如何通過基於智能手機應用中基於滑動使用模式 的 GPU 來節省 GPU 節能來協調節能，從而降低系統功耗。首先，我 們通過一個小的實驗來指出我們的想法。然後，我們提出了基於人類 敏銳度和滾動速度來設計 OLPD（OLED 像素禁用）和 DRS（動態分辨 率縮放）的算法。最後，基於每個組件的設計，我們分別分析了 OLPD 和 DRS 的功率節省水平，並提供了 OLED 顯示和 GPU 之間的協調政 策。在具有流行的交互式應用程序的商業智能手機上進行的實驗結果 表明，OLDS 可以實現大量的節能，同時保持可接受的圖像質量。

Mobile systems will increasingly feature emerging OLED displays equipped with extremely-high display resolution and density. In the past, most papers focused on reducing the OLED power consumption or power saving for GPUs respectively. This paper explores how to reduce the system power consumption by co-governing the power saving for OLED displays with power saving for GPUs based on sliding-based usage pattern on smartphone’s application. First, we point out our idea by a small experiment. Then, we propose the algorithm that is based on human acuity and scrolling speed to design for OLPD (OLED pixel disabling) and DRS (Dynamic resolution scaling). Finally, based on the design of each component, we analyze the power saving level of OLPD and DRS respectively and provide the co-governing policy between OLED display and GPU. The results of experiments conducted on commercial smartphone with popular interactive apps demonstrate that OLDS can achieve substantial energy savings, while preserving acceptable image quality.
