Energy-Efficient Computing: Datacenters, Mobile Devices, and Mobile Clouds



Energy consumption is a key design driver for electronic systems ranging from warehouse-size datacenters to battery-powered mobile devices to mobile clouds. It is well known that energy efficiency is best achieved by an application-specific mix of power-efficient hardware and runtime energy governance. Power efficient hardware requires low power devices, cell libraries, circuits, and architectures whereas effective energy governance needs significant hardware and software support e.g., to achieve dynamic power/performance scaling, power gating, core consolidation, and computation offloading. In my talk I will discuss three example problems to illustrate the range of low power solutions that can be employed and the kind of power savings which are achievable. These problems are: (i) Power-efficient resource management and job scheduling in a geo-distributed cloud infrastructure, (ii) Design of low-power application processors exploiting the temperature effect inversion of deeply scaled devices, and (iii) Energy-efficient computation offloading for deep neural networks in a mobile cloud computing environment. I will conclude my talk with a list of best power-efficient design practices. 



Massoud Pedram, received a Ph.D. in Electrical Engineering and Computer Sciences from the University of California, Berkeley in 1991. He holds 10 U.S. patents and has published four books and more than 650 archival and conference papers and book chapters. His research ranges from low power electronics, energy-efficient processing, and cloud computing to electrical energy storage systems, quantum computing, and superconductive electronics. For this research, Dr. Pedram and his students have received multiple conference and journal Best Paper awards. He has served on the technical program committees of many conferences in his field and was the founding Technical Program Co-chair of the 1996 International Symposium on Low Power Electronics and Design. Dr. Pedram is a recipient of the 1996 Presidential Early Career Award for Scientists and Engineers, a Fellow of the IEEE, an ACM Distinguished Scientist, and has served as the Editor-in-Chiefs of the ACM Transactions on Design Automation of Electronic Systems and the IEEE Journal on Emerging and Selected Topics in Circuits and Systems.  He received the 2015 IEEE Circuits and Systems Society Charles A. Desoer Technical Achievement Award for his contributions to modeling and design of low power VLSI circuits and systems, and energy efficient computing and the 2017 USC Viterbi School of Engineering Senior Research Award. Dr. Pedram received the Second Most Cited Author Award at the 20th Anniversary Int’l Symp. on Low Power Electronics and Design, Jul. 2015 and the Third Most Cited Author Award at the 50th anniversary of the Design Automation Conf., Jun. 2013.

Technology trends, requirements and challenges for ubiquitous self-powered IOT systems deployment



Always ON always sensing small form factor edge systems for internet of things (IOT) are becoming ubiquitous. Many applications require these tiny devices to be self-powered and maintenance-free. Hence they should be able to harvest energy from available ambient sources and should have low manufacturing cost. Millimeter-scale form factor systems have been developed in academia for the past few years. Small form factor edge systems are becoming commercially available. These systems are essential in today’s cyber physical world. We will introduce the available market and the trends driving this growth in IOT system deployments. That will be followed by typical system requirements for a typical self-powered IOT system. Challenges to realize such a dream IOT system will be discussed. We will present two approaches to system design, namely bottom-up and top-down. An X86-based tiny microcontroller unit (MCU) was designed to enable multiple IOT usages. This MCU followed a bottom-up approach – ultra-low power low cost MCU was designed first and then applied to IOT systems such as smart sensor tag for package tracking. The discussion will introduce another IOT system that followed a top-down usage-driven approach. In this case, an agricultural usage was chosen that required energy harvesting, X86-class edge computing, visual recognition on the edge, secure storage, secure wireless communication and ultra-low power maintenance free operation. An IOT system was architected for this usage and later demonstrated. We will conclude the presentation with comparison of these two distinct approaches to IOT system design.
