Note unusual time

In this talk, I will introduce the research areas of CAD group in Nano-Integrated Circuits and Systems Lab, E.E. Dept., Tsinghua University. The first research topic is the power and reliability aware design methodology along with the CMOS technology scaling, in which we focus on the modeling and mitigation techniques for leakage power and NBTI induced aging effect for nano-scale integrated circuits. The second research topic is how to design application specific hardware (multi/many-core) systems. We have tried to look at some interesting applications, and efficiently mapped them onto different hardware to get beggar energy/power efficiency. I will talk about a little bit more on our open source parallel implementation of sparse LU decomposition on both CPU and GPU ( For the third research direction, we try to explore the possible computation model of the future energy efficient computing system by leveraging the computation power of new devices. I will try to show you some progress on the approximated computation using memristor, and what we want to do in the next step.

Bio: Yu Wang is an Associate Prof. in EE Dept, Tsinghua University. He received his B.S. degree in 2002, and then Ph.D. degree with honor in 2007 from Tsinghua University. Dr. Wang’s research mainly focuses on parallel circuit analysis, low power and reliability aware system design methodology, and application specific hardware computing, especially for brain related topics.
