Titre: Low Power Asynchronous-Logic Circuit Design
Conférencier: Dr Gwee Bah Hwee , Nanyang Technological University, Singapour
Lieu: Concordia University, SGW Campus, EV 003.309 ,
Date et heure: mercredi le 30 septembre 2009 de 18:00 à 20:00

Résumé: Asynchronous-logic is an emerging methodology where the microprocessor will be increasingly asynchronous – 40% by 2020 from the present 11% (ITRS roadmap). It is an alternative design approach (as opposed to prevalent synchronous-logic) to ultra low power digital circuits and it could be robust to the process, voltage and temperature (PVT) variations for biomedical applications and the like. In this talk, an overview from the following perspectives will first be given: some pertinent requirements of biomedical applications, the current-art technology roadmap and its technology challenges, and a review of asynchronous-logic and synchronous-logic. Thereafter, the completed and on-going asynchronous-logic projects will be presented, in part, for the design of low power biomedical applications. These projects include a Fast Fourier Transform processor, an Intel-based 8051 microcontroller, a Motorola-based 24-digital signal processor, and an asynchronous electronic design automation tool. Finally, some potential projects by adopting asynchronous-logic will be discussed.

Références: Dr Bah-Hwee Gwee received his B.Eng. degree from University of Aberdeen, UK, in 1990. He received his M.Eng. and Ph.D. degrees from Nanyang Technological University (NTU), Singapore in 1992 and 1998 respectively. He is currently an associate professor in School of EEE, NTU. He has been working on a number of funded research projects amounting to SGD $5.3m (~ CAD $4m). He is the PI/co-PI of projects including the DARPA project from USA, the AUNP project from EU, Panasonic Semiconductor Corporation research grant, Linköping University (Sweden) – NTU research collaboration project, Singapore Defence Science Project and Academic Research Funded Projects.He was the Chairman of Singapore IEEE Circuits and Systems Chapter in 2005 and 2006. He is the committee member of IEEE CASS VLSI Systems TC, DSP TC, BioCAS TC and Life Science TC. He was the organizing committee of the IEEE Bio-CAS 2004, the IEEE APCCAS 2006 and the Programme Chair of ISIC 2007. He is a senior member of IEEE, an Associate Editor of journal of Circuits, Systems and Signal Processing and the IEEE CASS Distinguished Lecturer. His research interests include asynchronous circuit design, ultra-low power sub-threshold design, Class-D amplifier design and digital hearing aid design. He has several circuit design patents granted and started a Start-up Company in 2005.
