OS-level Power Management for Mobile Devices


Speaker: Professor Sung Woo Chung
Korea University, Seoul, Korea

Thursday, October 3, 2013, 11am - 12pm

Illinois Institute of Technology​, Stuart Building, Room 113.

 

Abstract

There have been numerous OS-level power management techniques, but most of them are not so realistic unfortunately (eg. too complicated to adopt or potential gain is marginal). On the other hand, power management techniques in off-the-shelf mobile devices are very basic such as changing frequency and voltage by looking at core frequency. In this talk, I will introduce smart OS-level power management techniques, which can be applicable to real mobile devices. My talk is composed of five parts as follows: 1) user-aware power management for display, 2) profile based DVFS for APs, 3) cost table based DVFS for APs, 4) thermal-aware DVFS for APs, and 5) battery-aware DVFS for APs. (All the results shown in this talk are based on real measurement (not simulation))

 

Bio 

Sung Woo Chung is an Associate Professor of Korea University. His research interests include architectural-/system-level power/thermal management. He is an Associate Editor of IEEE Transactions on Computers and he also serves as processor architecture track program co-chair of ICCD 2013. He received his B.S. degree in Computer Engineering, his Ph.D. degree in Electrical and Computer Engineering from Seoul National University, Seoul, Korea in 1996 and 2003, respectively. He worked as an academic visitor for IBM T.J. Watson Research Center, Yorktown Heights, NY, in 2002. From 2003 to 2005, He worked for Samsung Electronics as a senior engineer. In 2005, He worked as a research scientist in University of Virginia, Charlottesville. In 2009, He spent his sabbatical at Northwestern University.
