About the Authors

Carl Hamacher received the B.A.Sc. degree in Engineering Physics from the University ofWaterloo, Canada, the M.Sc. degree in Electrical Engineering from Queen’s University, Canada, and the Ph.D. degree in Electrical Engineering from Syracuse University, New York. From 1968 to 1990 he was at the University of Toronto, Canada, where he was a Professor in the Department of Electrical Engineering and the Department of Computer Science. He served as director of the Computer Systems Research Institute during 1984 to 1988, and as chairman of the Division of Engineering Science during 1988 to 1990. In 1991 he joined Queen’s University, where is now Professor Emeritus in the Department of Electrical and Computer Engineering. He served as Dean of the Faculty of Applied Science from 1991 to 1996. During 1978 to 1979, he was a visiting scientist at the IBM Research Laboratory in San Jose, California. In 1986, he was a research visitor at the Laboratory for Circuits and Systems associated with the University of Grenoble, France. During 1996 to 1997, he was a visiting professor in the Computer Science Department at the University of California at Riverside and in the LIP6 Laboratory of the University of Paris VI.

His research interests are in multiprocessors and multicomputers, focusing on their interconnection networks.

Zvonko Vranesic received his B.A.Sc., M.A.Sc., and Ph.D. degrees, all in Electrical Engineering, from the University of Toronto. From 1963 to 1965 he worked as a design engineer with the Northern Electric Co. Ltd. in Bramalea, Ontario. In 1968 he joined the University of Toronto, where he is now a Professor Emeritus in the Department of Electrical & Computer Engineering. During the 1978–79 academic year, he was a Senior Visitor at the University of Cambridge, England, and during 1984-85 he was at the University of Paris, 6. From 1995 to 2000 he served as Chair of the Division of Engineering Science at the University of Toronto. He is also involved in research and development at the Altera Toronto Technology Center.

His current research interests include computer architecture and field-programmable VLSI technology.

He is a coauthor of four other books: Fundamentals of Digital Logic with VHDL Design, 3rd ed.; Fundamentals of Digital Logic with Verilog Design, 2nd ed.; Microcomputer Structures; and Field-Programmable Gate Arrays. In 1990, he received theWighton Fellowship for “innovative and distinctive contributions to undergraduate laboratory instruction.” In 2004, he received the Faculty Teaching Award from the Faculty of Applied Science and Engineering at the University of Toronto.

Safwat Zaky received his B.Sc. degree in Electrical Engineering and B.Sc. in Mathematics, both from Cairo University, Egypt, and his M.A.Sc. and Ph.D. degrees in Electrical Engineering from the University of Toronto. From 1969 to 1972 he was with Bell Northern Research, Bramalea, Ontario, where he worked on applications of electro-optics and magnetics in mass storage and telephone switching. In 1973, he joined the University of Toronto, where he is now Professor Emeritus in the Department of Electrical and Computer Engineering. He served as Chair of the Department from 1993 to 2003 and as Vice-Provost from 2003 to 2009. During 1980 to 1981, he was a senior visitor at the Computer Laboratory, University of Cambridge, England.

He is a Fellow of the Canadian Academy of Engineering. His research interests are in the areas of computer architecture, digital-circuit design, and electromagnetic compatibility. He is a coauthor of the book Microcomputer Structures and is a recipient of the IEEE Third Millennium Medal and of the Vivek GoelAward for distinguished service to the University of Toronto.

Naraig Manjikian received his B.A.Sc. degree in Computer Engineering and M.A.Sc. degree in Electrical Engineering from the University of Waterloo, Canada, and his Ph.D. degree in Electrical Engineering from the University of Toronto. In 1997, he joined Queen’s University, Kingston, Canada, where he is now an Associate Professor in the Department of Electrical and Computer Engineering. From 2004 to 2006, he served as Undergraduate Chair for Computer Engineering. From 2006 to 2007, he served as Acting Head of the Department of Electrical and Computer Engineering, and from 2007 until 2009, he served as Associate Head for Student and Alumni Affairs. During 2003 to 2004, he was a visiting professor at McGill University, Montreal, Canada, and the University of British Columbia. During 2010 to 2011, he was a visiting professor at McGill University.

His research interests are in the areas of computer architecture, multiprocessor systems, field-programmable VLSI technology, and applications of parallel processing.
