Mobile games typically exhibit inherent behavioral dynamism, which existing governor policies are unable to exploit effectively to manage CPU/GPU DVFS policies. To overcome this problem, we present HiCAP: a Hierarchical Finite State Machine (HFSM) based CPU-GPU governor that models the dynamic behavior of mobile gaming workloads, and applies a cooperative, dynamic CPU-GPU frequency-capping policy to yield energy efficiency adapting to the game's inherent dynamism. Our experiments on a large set of 37 mobile games exhibiting dynamic behavior show that our CAP dynamic governor policy achieved substantial energy efficiency gains of up to 18% improvement in energy-per-frame over existing governor policies, with minimal degradation in quality.","PeriodicalId":142716,"journal":{"name":"Proceedings of the 2016 International Symposium on Low Power Electronics and Design","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126215459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But frequent user interactions and limited battery capacity make low-power approaches highly required in AMOLED displays more and more. In this paper, we propose a novel dynamic voltage scaling (DVS) method based on scene change detection for video playback on a mobile AMOLED display panel. This method first employs the entropies of Y, Cb, and Cr components in the YCbCr color space for macroblocks in each video frame to detect the scene change and determine when to do DVS. And then it associates the luminance with the Y component and extracts the relationship between Cb and Cr components and the supply voltage to the display panel to determine how much to do DVS. We implemented this method for an MPEG4/H.264 player on an evaluation board with a mobile AMOLED display panel. Experimental results show that the proposed algorithm achieves on average 19.7% power saving compared to the original video on an AMOLED display. Also, the proposed algorithm recovered the luminance of the AMOLED display from 93% to 96%.","PeriodicalId":142716,"journal":{"name":"Proceedings of the 2016 International Symposium on Low Power Electronics and Design","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125386615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, reducing the static power of execution units is not clear based on two reasons. First, the very long idle time of execution units in GPGPU is fragmented in to many short periods. Second, these units are very critical to total performance. In this paper, we propose a method to reduce the static power without any performance overhead. We utilize out-of-order execution of instructions to make the idle period of execution units much longer. Experimental results show that our proposal improves over the state-of-the-art in terms of power and performance by 25% and 8%, on average, respectively.","PeriodicalId":142716,"journal":{"name":"Proceedings of the 2016 International Symposium on Low Power Electronics and Design","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130857581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we present an approach to leverage existing voltage regulators to recover this energy from the disabled voltage-domain back into the supply using a low-overhead all-digital runtime control system.
