ECE Seminar with Ajay Joshi
ECE Seminar with Ajay JoshiBoston UniversityDepartment of Electrical and Computer Engineering Refreshments will be served outside of PHO 339 at 3:45 pm. Designing Energy-efficient Reliable and Secure Systems: From Emerging Devices to Bio-inspired ArchitecturesAbstract: Over the past two decades, the general-purpose compute capacity of the world increased by 1.5x every year, and we will need to maintain this rate of growth to support the increasingly sophisticated data-driven applications of the future. However, a sustenance of this growth in compute capacity will correspondingly lead to large power consumption. Moreover, as we move into the nanoscale CMOS regime providing reliable and secure operation of these computing systems is going to be increasingly challenging. Hence, now more than ever, there is a critical need to explore new techniques at all levels in the hierarchy to design energy-efficient, reliable and secure computing systems.Over the past 6 years, my research group has developed a variety of architecture-level and circuit-level solutions to enable energy-efficient, reliable and secure operation of computing systems. In this talk, I will first provide an overview of our work on design and run-time management of silicon-photonic networks and electrical networks to provide energy-efficient communication in manycore systems. I will then present the design of a neural network-based accelerator architecture, which can accelerate application execution and in turn improve energy efficiency of the computing system. In terms of circuit-level solutions, I will present a novel approach of using communications-inspired equalization techniques for designing ultra-low power and reliable circuits for biomedical applications. This will be followed by a discussion of imaging techniques and ECC techniques that we have developed to enable secure and reliable operation of logic and memory circuits. Speaker bio:Ajay Joshi received his Ph.D. degree from the ECE Department at Georgia Tech in 2006. He then worked as a postdoctoral researcher in the EECS Department at MIT until 2009. He is currently an Assistant Professor with the ECE Department at Boston University. His research interests span across various aspects of VLSI design including circuits and architectures for communication and computation, and emerging device technologies including silicon photonics and memristors. He received the NSF CAREER Award in 2012 and Boston University ECE Department's Award for Excellence in Teaching in 2014.
