Trevor Mudge received a Ph.D. in Computer Science from the University of Illinois. Since then he has been at the University of Michigan. He was named the Bredt Professor of Engineering after a ten year term as Director of the Advanced Computer Architecture Laboratory — a group of a dozen faculty and 80 graduate students. He is author of numerous papers on computer architecture, programming languages, VLSI design, and computer vision. He has also chaired 42 theses in these areas. He is a Fellow of the IEEE, a member of the ACM, the IET, and the British Computer Society.

With power and cooling becoming an increasingly costly part of the operating cost of a server, the old trend of striving for higher performance with little regard for power is over. Emerging semiconductor process technologies, multicore architectures, and new interconnect technology provide an avenue for future servers to become low power, compact, and possibly mobile. In our talk we examine three techniques for achieving low power: 1) Near threshold operation; 2) 3D die stacking; and 3) replacing DRAM with Flash memory.
