Başlık : Efficient and Secure On-Chip Power Delivery
Efficient generation, distribution, and management of on-chip supply voltages require fundamental changes to the power delivery process to provide increased current within a constant power budget in the next generation ICs. Recently, the proliferation of high-density on-chip voltage regulators in high performance ICs has enabled new circuit topologies and control techniques. Distributed power delivery has become a promising alternative to existing power delivery techniques, efficiently providing high quality power.
In this talk, some of the recent research results on the design and management of on-chip power delivery systems will be presented. Existing efforts from industry related to distributed power delivery will be reviewed. A recently proposed on-chip power delivery architecture, converter-gating, will be discussed. In this technique, individual voltage converter stages are adaptively turned on and turned off based on the workload information to concurrently achieve: i) high power efficiency and ii) high security against side-channel attacks. A brief background on side-channel attacks against integrated circuits will also be provided. Bio
Selçuk Köse received the B.S. degree in electrical and electronics engineering from Bilkent University, Ankara, Turkey, in 2006, and the M.S. and Ph.D. degrees in electrical engineering from the University of Rochester, Rochester, New York, in 2008 and 2012, respectively.
