Energy-Efficient Memory-Centric Accelerator Design for Mobile/Edge-based AI Inference
Prof. Po-Tsang Huang, National Chiao Tung University, Taiwan

Abstract: Deep convolutional neural networks (CNNs) are widely used in feature classification, recommender systems and image recognition. Nevertheless, deep CNNs are difficult to be fully deployed to edge/mobile/IoT devices because of both memory-intensive and computation-intensive workloads. The energy efficiency of CNNs is dominated by convolution computation and off-chip memory (DRAM) accesses, especially for DRAM accesses. In this tutorial, we will outline the important bottlenecks and solutions for energy-efficient computing hardware of mobile/edge-based AI inference, notably the end of Moore’s Law and the memory wall problem. We will then discuss several memory-centric accelerator design approaches and interconnection architectures using advanced technologies, including TSV 3D-SRAM, 3D-DRAM, monolithic 3D-SRAM and computation-in-memory circuits.

HuangBiography: Po-Tsang Huang received the B.Sc., M.Sc., and Ph.D. degrees from the Department of Electronics Engineering, National Chiao Tung University (NCTU), Hsinchu, Taiwan, in 2002, 2004, and 2010, respectively. From 2011 to 2014, he was an assistant research fellow at NCTU. From 2015 to 2016, he was an associate research fellow at NCTU and a visiting scholar at University of California, Los Angeles (UCLA). Currently, he is an assistant professor at International College of Semiconductor Technology, NCTU. His research interests focus on low-power digital IC design, hardware design for AI and machine learning applications, embedded memory design, low-power TSV 2.5D/3D integration, monolithic 3DIC and low-power SoC/SiP designs with particular emphasis on inter-chip/intra-chip data communications & memory sub-systems.

Efficient Power Design for IoT/IIoT & 5G Applications
Brian Zahnstecher, Principal, PowerRox LLC, USA

Abstract: In general, the success of any electronics deployment is dependent on the effective design and implementation of its power electronics. When it comes to battery-operated devices or other things in the Internet of Things (IoT) / Industrial IoT (IIoT), a highly-efficient design must be realized to optimize energy consumption for various reasons, whether it be to preserve battery life, enable a smaller form-factor, or even be the difference between the ability to viably deploy the application or not. As we move into the 5G era and anticipate the deployment of many billions or even a trillion devices, this focus is of critical importance at all levels of deployment from the tiniest systems to the largest networks. The tutorial will cover above issues.

Annealing Processing and Emerging Non-volatile Memory for AI Chips
Prof. Takayuki Kawahara, Tokyo University of Science, Japan

Abstract: First, the importance of processing on the edge is outlined. This is followed by a discussion of neural networks and deep learning as part of the development trends of AI chips, after which the incorporation of learning functions, sparseness, and accuracy of calculation is discussed. Next, it moves on to discuss the development trends of emerging nonvolatile memories, especially STT-RAM and SOT-RAM, that are vital for low power consumption and examples of applications to AI. Finally, the development of the fully-coupled-spin annealing AI chip that helps solve combinatorial optimization problems is disclosed. This represents a new paradigm in edge computing.

KawaharaBiography: Takayuki Kawahara received B.S. and M.S. degrees in Physics and a Ph.D. degree in Electronics from Kyushu University, Fukuoka, Japan in 1983, 1985, and 1993. From 1997 to 1998, he was a visiting researcher at the Electronics Laboratory (LEG) in the Swiss Federal Institute of Technology, Lausanne (EPFL). Since joining the Central Research Laboratory (CRL), Hitachi Ltd. in 1985, he has made fundamental contributions in the field of low-power memories. In the DRAM area, he initiated subthreshold-current reduction by gate-source self-reverse biasing in 1993. He also pioneered the charge-recycling scheme, which is now widely applied in various circuits. In flash memory, he and his team developed a 128-Mb chip. He also reported the world’s first fully functional 2-Mb STT-RAM proto chip in 2007, and his team developed FD-SOI SRAM circuitry with back-gate control. After leaving CRL as a Chief Researcher, in 2014, he became a professor in the Department of Electrical Engineering at the Tokyo University of Science. The main focus of his laboratory is sustainable electronics. His research group carries out cutting-edge research on ultra-low-power artificial intelligence (AI) devices and circuits, sensor and AI signal processing, and spin-current applications.

He was an IEEE SSCS distinguished lecturer in 2008/2009 and the FE regional chair of IEEE ISSCC 2009/2010. He is a recipient of the 9th (2009) Yamazaki-Teiichi Prize, the 2014 IEICE Electronics Society Award, and the Prize for Science and Technology (Development Category) in the FY2017 Commendation for Science and Technology by the Minister of Education, Culture, Sports, Science and Technology. He is also an IEEE Fellow.

Portable and Scalable High Voltage Circuits for Automotive Applications in BiCMOS Processes
Dr. Sri Navaneeth Easwaran, Texas Instruments Inc, USA.

Abstract: Systems-On-Chip (SoC) are increasing in automotive applications like airbag, braking, power steering, and motor drivers. Automotive ICs are similar to conventional analog circuits used in consumer electronics, but they have to handle a wide range of input voltage (5V to 40V) and currents (30mA to 4A) and withstand -18V levels. This tutorial introduces the SoC requirements, design of high side and low side drivers, R-L-C loads, thermal and electrical Safe Operating Area, diagnostics, transceivers, biasing techniques to ensure correct turn ON/OFF behavior, and parasitic bipolars. Finally, the tutorial presents the scalability and programmability of these designs.
