Professor Dennis Sylvester visited our group on June 12.
He gave a seminar talk at the Research Bldg. No.8, Kyoto University.
Speaker: Prof. Dennis Sylvester (University of Michigan, Ann Arbor)
Title: Ultra Low Power System Design Challenges and Solutions
Abstract: This talk describes a design approach that focuses on
system-level energy minimization to achieve nanowatt-level complete
microsystems. Starting with proper technology selection, the approach
systematically targets power minimization in critical design building
blocks including timers, memories, processors, and interface circuits.
Near-threshold circuits are a key element in designing such ultra-low
power blocks and the state of the art in ultra-low power design of
these components will be reviewed, while areas requiring further
reductions will be highlighted. Finally, the feasibility of major
(order of magnitude) advances in low power circuits to enable energy
autonomous microsystems will be briefly discussed, including
technology-circuit co-optimization and accelerator-based design.
