Multiple-Base Number System

Vassil S. Dimitrov earned a Ph.D degree in applied mathematics from the Bulgarian Academy of Sciences in 1995. Since 1995, he has held postdoctoral positions at the University of Windsor, Ontario (19961998) and Helsinki University of Technology (19992000). From 1998 to 1999, he worked as a research scientist for Cigital, Dulles, Virginia (formerly known as Reliable Software Technology), where he conducted research on different cryptanalysis problems. Since 2001, he has been an associate professor in the Department of Electrical and Computer Engineering, Schulich School of Engineering, University of Calgary, Alberta. His main research areas include implementation of cryptographic protocols, number theoretic algorithms, computational complexity, image processing and compression, and related topics. Graham Jullien recently retired as the iCORE chair in Advanced Technology Information Processing Systems, and the director of the ATIPS Laboratories, in the Department of Electrical and Computer Engineering, Schulich School of Engineering, at the University of Calgary. His long-term research interests are in the areas of integrated circuits (including SoC), VLSI signal processing, computer arithmetic, high-performance parallel architectures, and number theoretic techniques. Since taking up his chair position at Calgary, he expanded his research interests to include security systems, nanoelectronic technologies, and biomedical systems. He was also instrumental, along with his colleagues, in developing an integration laboratory cluster to explore next-generation integrated microsystems. Dr. Jullien is a fellow of the Royal Society of Canada, a life fellow of the IEEE, a fellow of the Engineering Institute of Canada, and until recently, was a member of the boards of directors of DALSA Corp., CMC Microsystems, and Micronet R&D. He has published more than 400 papers in refereed technical journals and conference proceedings, and has served on the organizing and program committees of many international conferences and workshops over the past 35 years. Most recently he was the general chair for the IEEE International Symposium on Computer Arithmetic in Montpellier in 2007, and was guest coeditor of the IEEE Proceedings special issue System-on-Chip: Integration and Packaging, June 2006. Roberto Muscedere received his BASc degree in 1996, MASc degree in 1999, and Ph.D in 2003, all from the University of Windsor in electrical engineering. During this time he also managed the microelectronics computing environment at the Research Centre for Integrated Microsystems (formally the VLSI Research Group) at the University of Windsor. He is currently an associate professor in the Electrical and Computer Engineering Department at the University of Windsor. His research areas include the implementation of high-performance and low-power VLSI circuits, full and semicustom VLSI design, computer arithmetic, HDL synthesis, digital signal processing, and embedded systems. Dr. Muscedere has been a member of the IEEE since 1994.
