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.
