Abstract:
This talk presents several designs of energy-efficient microprocessors that implement many of the techniques for operation in a very wide voltage range. A particular implementation is based on an open Berkeley RISC-V architecture. To enable agile dynamic voltage and frequency scaling, with high energy efficiency the design implements an integrated switched-capacitor DC-DC converter. A custom-designed SRAM-based cache operates in a wide 0.45-1V supply range. Techniques that enable
low-voltage SRAM operation include 8T cells, assist techniques and differential read. Architectural resiliency techniques include the use of error correction and dynamic column redundancy.

Bio:
Borivoje Nikolić received the Dipl.Ing. and M.Sc. degrees in electrical engineering from the University of Belgrade, Serbia, in 1992 and 1994, respectively, and the Ph.D. degree from the University of California at Davis in 1999. In 1999, he joined the Department of Electrical Engineering and Computer Sciences, University of California at Berkeley, where he is now a Professor. His research activities include digital, analog and RF integrated circuit design and VLSI implementation of communications and signal processing algorithms. He is co-author of the book Digital Integrated Circuits: A Design Perspective, 2nd ed, Prentice-Hall, 2003. Dr. Nikolić received many awards in his career, including the NSF CAREER award in 2003, and the best paper awards at the IEEE International Solid- State Circuits Conference, Symposium on VLSI Circuits, IEEE International SOI Conference, European Solid-State Circuits Research Conference, European Solid-State Device Research Conference, and the ACM/IEEE International Symposium of Low- Power Electronics.
