A power management scheme with activity localization can reduce the number of transitions between power-on and power-off modes with re-scheduling and bundling task procedures. And autonomously standby mode transition control selects the optimum standby mode of microcontrollers, reducing total power consumption. We demonstrate with evaluation board as a use case of IoT applications, observing 91% power reductions by adopting task scheduling and autonomously standby mode transition control combination.","PeriodicalId":439955,"journal":{"name":"2017 IEEE Symposium in Low-Power and High-Speed Chips (COOL CHIPS)","volume":"314 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122805814","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}

The IBE is designed to have both efficiency and flexibility to support various emerging applications for future sensor hub SoCs in addition to the sensor fusion and machine learning algorithm (SVM) which are the target applications of the SLH200. With regard to the SLH200 SoC, the IBE was fabricated in the Global Foundry 55nm process, and the performance and power evaluation with IBE have been performed with the evaluation board of the SLH200 SoC. The evaluation results show that the proposed IBE can achieve up to 31.3× faster speed for target kernel operation and 4× faster speed for the target application (SVM polynomial). It reduces the energy consumption up to 75% as well.","PeriodicalId":439955,"journal":{"name":"2017 IEEE Symposium in Low-Power and High-Speed Chips (COOL CHIPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129824261","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}

One technical issue is that, since the energy cost of write access requests for an STT-RAM LLC is expensive, the total energy consumption of the STT-RAM LLC may increase for some write-intensive applications. Therefore, this paper proposes an Adjacent-Line-Merging Writeback Scheme. The proposed scheme dynamically merges two adjacent lines and write them back to the STT-RAM LLC as one line. The evaluation results show that the proposed scheme can reduce the energy consumption by up to 28%, and 10.4% on average.","PeriodicalId":439955,"journal":{"name":"2017 IEEE Symposium in Low-Power and High-Speed Chips (COOL CHIPS)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132058855","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}

There has been a shift in care prevention, diagnosis and treatment which has decreased the importance of traditional methods of care delivery. We have put a great deal of effort into the definition of the structure of the volume and in the sequence of the contributions, so that those in search of a specific reading path will be rewarded. To this end we have divided the different chapters into six main sections: 1. Editorial: This introductory text expresses the position of the Editors - Brenda K. Wiederhold and Giuseppe Riva - about the focus of this year issue; 2. Critical Reviews: These chapters summarize and evaluate emerging cybertherapy topics, including technology-enhanced rehabilitation, Interreality, and Intersubjectivity; 3. Evaluation Studies: These chapters are generally undertaken to solve some specific practical problems and yield decisions about the value of cybertherapy interventions; 4. Original Research: These chapters research studies addressing new cybertherapy methods or approaches; 5.\u0000\u0000\u0000CLINICAL OBSERVATIONS\u0000These chapters include case studies or research protocols with long-term potential. 6. Work in Progress: These chapters include papers describing a future research work. For both health professionals and patients, the selected contents will play an important role in ensuring that the necessary skills and familiarity with the tools are available, as well as a fair understanding of the context of interaction in which they operate. In conclusion, this volume underlines how cybertherapy has started to make progress in treating a variety of disorders. However, there is more work to be done in a number of areas, including the development of easy-to-use and more affordable hardware and software, the development of objective measurement tools, the need to address potential side effects, and the implementation of more controlled studies to evaluate the strength of cybertherapy in comparison to traditional therapies. We are grateful to Chelsie Boyd from the Virtual Reality Medical Institute for her work in collecting and coordinating chapters for this volume. We sincerely hope that you will find this year's volume to be a fascinating and intellectually stimulating read. We continue to believe that together we can change the face of healthcare. Brenda K.
