However, energy-efficiency of wearable-end sensor nodes becomes a big issue for user experience in these applications. Huge volume of biodata sensing and intelligent bioevent analysis rapidly drain the battery storage in sensor node. Therefore, energy-efficiency of wearable sensor node needs to be tackled in urgent. With more energy savings, the lifetime of wearable system can be prolonged to reduce the recharging trouble. Better energy-efficiency can even improve the form factor of wearable nodes.To address the energy-efficiency challenge, we proposed a holistic compressed sensing (CS) based framework to jointly optimize the sensing architecture and computing architecture. We design our sensing architecture from three aspects, including parameter agility, information screen and signal dynamics, to exploit the opportunity of energy savings. We integrate circuit-level design parameter into CS architecture to explore better trade-off between energy and performance with the help of time-efficient design space exploration algorithm. We develop an information screening module to complete the low-effort data analysis task in the sensor node to avoid the energy-hungry wireless transmission. We also propose dynamic knob to make the sensing architecture adapting to the data dynamics, which is a common case in biosiganl processing. Finally, we investigate the optimization of computing architecture by cross-end implementation of the finer-grained computing primitives.Our contribution is three-fold: 1) We divide the intractable energy-efficiency problem of wearable system into two easier sub-parts, sensing and computing. We optimize our design from these two aspects jointly; 2) We model and develop algorithms to guide the improvements of the architecture and design; 3) We propose a holistic solution to tackle all the challenges and make large-step improvement on energy efficiency of wearable system."]},{"key":"dc:format","label":"Dc Format","values":["application/pdf"]},{"key":"dc:title","label":"Title","values":["Cooperated Sensing and Computing for Energy-Efficient Wearables"]}]}],"canonical_facts":{"dc:contributor":["Xu, Wenyao","Computer Science and Engineering"],"dc:creator":["Wang, Aosen; 0000-0002-9825-9330"],"dc:date":["2018-10-26T02:54:35Z","2018","2018-07-07 15:55:46"],"dc:description":["Ph.D.","Nowadays, miniature and intelligence make wearable system advance to the leading-edge applications, such as telemedicine, patient rehabilitation and chronic disease analysis.
