EE 598: ELECTRICAL ENGINEERING RESEARCH SEMINAR COURSE #10

Speaker: Lizhong Chen, PhD Candidate, Electrical Engineering USC Viterbi School of Engineering

Talk Title: Energy-efficient On-chip Networks for Many-core Processors

Series: EE598 Seminar Course

Abstract: Energy-efficient processors are of paramount importance to designing computing systems that deliver superior performance-cost trade-offs. However, as the key communication subsystem of many-core processors, the on-chip network consumes a substantial percentage of the chip’s power and energy. In this talk, we analyze the energy consumption of on-chip networks and discuss the opportunities and challenges in reducing it, with an emphasis on minimizing static power by developing effective power-gating schemes. Two novel designs, namely node-router decoupling and proactive power-gating are proposed to provide architectural support for effective power-gating. These designs not only reduce static power, but also open up new opportunities for optimizing power-gating that is particularly needed for current on-chip networks.

Biography: Lizhong Chen is a PhD candidate working with Prof. Timothy Pinkston in the Ming Hsieh Department of Electrical Engineering at the University of Southern California, Los Angeles. His research focuses on energy-efficient and high-performance interconnection networks for chip multiprocessors and super-computers. His research has been published at top venues in computer architecture, including MICRO, HPCA and IPDPS. He received his BS degree in Electrical Engineering from Zhejiang University in 2009 and MS degree in Electrical Engineering from USC in 2011.
