With increasing demand for low-power and portable systems, energy efficient design solutions are sought at all levels of the design abstraction. In this talk I will explore adaptation and resiliency in digital circuits, both logic and memory, and their suitability in reducing the voltage and frequency guardbands. Different design solutions for process and environment sensing, error monitoring and correcting on a research microprocessor will be presented. I will address various aspects of calibration-less sensor design and how they can be coupled to adaptive voltage and clock controllers to provide energy optimal compute and memory solutions.
Dr Arijit Raychowdhury received his Ph.D. degree in Electrical and Computer Engineering from Purdue University, IN in 2007. He is currently a staff scientist in the Circuits Research Lab, Intel Corporation. Previously he has worked as an Analog Circuit Designer with Texas Instruments. His research interests include digital and mixed-signal circuit design, device modeling and various aspects of device-circuit interactions and co-design. He has authored/coauthored more than fifty papers in refereed conferences and journals and holds fourteen patents. Dr. Raychowdhury has received multiple academic excellence awards, two best paper awards, the Meissner Fellowship from Purdue University, the Intel PhD Fellowship Award, and the Dimitri N. Chorafas Award for the best doctoral thesis. He has served on the Technical Program Committee of several conferences, NSF panels and is an industry liaison for multiple SRC and FCRP programs.
