Cell sizing and transistor threshold selection, as well as datapath and clock buffering, are some of the tools available for design optimization. At the moment, design optimization methods are integrated into EDA tools and applied incrementally in various parts of the flow, while the optimal order of their application is yet to be determined. In this work, we rely on reinforcement learning – through the use of the Multi-Armed Bandit model for decision making under uncertainty – to automatically suggest online which optimization heuristic should be applied to the design. The goal is to improve the performance metrics based on the rewards learned from the previous applications of each heuristic. Experimental results show that automating the process of design optimization with machine learning not only results in designs that are close to the best-published results derived from deterministic approaches, but it also allows for the execution of the optimization flow without any human in the loop, and without any need for offline training of the heuristic-orchestration algorithm.","PeriodicalId":430458,"journal":{"name":"2019 29th International Symposium on Power and Timing Modeling, Optimization and Simulation (PATMOS)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123831829","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, frequent charge and discharge cycles cause aging effects in the battery, which results in a loss of capacity and life time.Power-neutral transient computing systems avoid energy buffers by powering the load by the harvester directly. Usually, the power outputs of energy harvesters rely on arbitrary and transient environmental excitations. The resulting power losses are handled by checkpointing, where the volatile system state is backed up using non-volatile memories. The timely detection of upcoming power losses is essential for a reliable checkpointing process. Early detections allow a proactive power loss handling, which is important to ensure the finalization of atomic operations. However, common voltage threshold-based methods only allow short-term power loss detections since they do not adapt to the dynamics of the harvester.In this paper we propose a new methodology that allows an early power loss detection by exploiting physical characteristics of the harvester. The proposed approach points out new opportunities for transiently-powered devices, as it allows an adaptive and harvester-aware computing. We show how it facilitates a proactive scheduling that is used to ensure a successful finalization of atomic operations.","PeriodicalId":430458,"journal":{"name":"2019 29th International Symposium on Power and Timing Modeling, Optimization and Simulation (PATMOS)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131259705","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}

Worldwide, agriculture accounts to 69% of total water usage, while industry accounts for 23%, and urban use to 8%. In Greece, a rural development model and poor farming practices have resulted in an overwhelming 83% of total water consumption to be directed to farming uses. Furthermore, excessive use of water in agriculture combined with existing pesticides and fertilizers usage levels creates exponential problems in the water cycle in Greece. Taking into account the above challenges, the AREThOU5A Project aims to exploit the state-of-the-art technologies and, in particular, the emerging developments in the field of Internet of Things (IoT) as a means to promote rational use of water resources in agriculture. In particular, AREThOU5A Project aims at accelerating penetration of low-power wide-access (LPWA) technologies through a series of research and innovation actions focusing on the design, development, operation and commercial exploitation of relevant hardware/software & IoT applications. Preliminary results of the AREThOU5A Project are depicted and future remarks are outlined.","PeriodicalId":430458,"journal":{"name":"2019 29th International Symposium on Power and Timing Modeling, Optimization and Simulation (PATMOS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127876512","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}
