Sudhakar Yalamanchili earned his B.E. degree in Electronics from Bangalore University (1978), and the M.S. and Ph.D. degrees in Electrical and Computer Engineering from the University of Texas at Austin (1980,1984). After graduation he joined Honeywell’s Systems and Research Center in Minneapolis where he served as the principal investigator for projects in the design and analysis of multiprocessor architectures for embedded applications. While at Honeywell, Dr. Yalamanchili also served as an adjunct faculty and taught in the Department of Electrical Engineering at the University of Minnesota. He joined the ECE faculty at Georgia Tech in 1989 where he is now Regents Professor and Joseph M. Pettit Professor of Computer Engineering. He is the author of VHDL Starters Guide, 2nd edition, Prentice Hall 2004, VHDL: From Simulation to Synthesis, Prentice Hall, 2000, and co-author with J. Duato and L. Ni, of Interconnection Networks: An Engineering Approach, Morgan Kaufman, 2003.
