Talk Title: Energy Harvesting and Remote Power Delivery for Ultra-low Power Applications
Abstract: Providing a constant and perpetual energy source is a key design challenge for ultra-low power applications such as remote sensing networks and implantable medical devices. Harvesting energy from the surrounding is one of the possible solutions. Delivering energy remotely from outside through different wireless media is another feasible solution. In this talk, we will present the power management systems that are required to support energy harvesting and remote power delivery for these applications, and discuss the design challenges.
Biography: Chi-ying Tsui received his B.S. degree in Electrical Engineering from the University of Hong Kong and Ph.D. degree in Computer Engineering from the University of Southern California in 1994. He joined the Department of Electronic and Computer Engineering, Hong Kong University of Science and Technology in 1994 and is currently a full professor in the department.
His research interests include designing VLSI architectures for low power multimedia and wireless applications, developing power management circuits and techniques for embedded portable devices and ultra-low power systems. He has published more than 170 referred publications and holds 10 US patents on power management, VLSI and multimedia systems. He received the best paper awards from the IEEE Transactions on VLSI Systems in 1995, IEEE ISCAS in 1999, IEEE/ACM ISLPED in 2007, and IEEE DELTA in 2008, CODES in 2012. He also received the Design Awards in the IEEE ASP-DAC University Design Contest in 2004 and 2006. He also co-founded a few start-up companies, one of which is public-listed in the Hong Kong Stock Exchange.

A Power Efficient Reconfigurable System-in-Stack: 3D Integration of Accelerators, FPGAs, and DRAM

Talk Title: A Power Efficient Reconfigurable System-in-Stack: 3D Integration of Accelerators, FPGAs, and DRAM
Abstract: Increasing computing power efficiency has become more important as more applications are moving to mobile platforms, which tend to have a limited power available. Being able to perform a wide variety of computations efficiently is especially important for power constrained embedded applications such as unmanned aerial vehicles (UAVs), which may not be able to send the data out for processing and must perform some of the processing on-board. This paper describes a 3D FPGA-DRAM architecture that can not only deliver the necessary flexibility, by using FPGAs, but also provide the computing efficiency in the form of floating-point arithmetic accelerators that is required for UAVs. We examine the efficiency of this system in 65 nm, 90 nm, and 130nm CMOS technologies and report simulation results showing a peak computing efficiency of 28.94GFLOPs/W for a 4,096 point 1 dimensional FFT and 25.03 GFLOPs/W for a 1,024 point ? 1,024 point 2 dimensional FFT.
Biography: Dr. Aravind Dasu is a Computer Scientist at the USC Information Sciences Institute in Arlington, Virginia. He received a PhD in Electrical Engineering from Arizona State University in 2004 and has since worked in the area of reconfigurable computing. His current specialization is in 3D stacking, trusted hardware, and architecture design for FPGAs. Over the past 16 years he has been a PI, CoPI, and Key personnel in R&D projects funded by NASA, Micron, ARM, Motorola, DoE, Lockheed Martin, Utah Governors Office , and DARPA with over $6,000,000 in research grants. He has over forty publications, supervised several graduate students & full time staff. He has served various government agencies such as NASA, the NSF, the National Nuclear Security Administration, and the Department of Energy for program and proposal reviews. His current business development focus is an initiative to build a Center of Excellence in 3D stacked adaptive computing at USC & ISI through strategic relationships with the Department of Defense, Intelligence Community, and Industry.
