David A. Patterson (University of California at Berkeley) has been teaching computer architecture at the University of California, Berkeley, since joining the faculty in 1977, and he holds the Pardee Chair of Computer Science. His teaching has been honored by the ACM, the IEEE, and the University of California. Patterson has also received the 1995 IEEE Technical Achievement Award for contributions to RISC and the 1999 IEEE Reynold B. Johnson Information Storage Award for contributions to RAID. He is a member of the National Academy of Engineering and is a fellow of both the ACM and the IEEE. In the past, he has been chair of the CS division in the EECS department at Berkeley, the ACM SIG in computer architecture, and the Computing Research Association.
At Berkeley, Patterson led the design and implementation of RISC I, likely the first VLSI Reduced Instruction Set Computer. This research became the foundation of the SPARC architecture, currently used by Sun Microsystems, Fujitsu, and others. He was also a leader of the Redundant Arrays of Inexpensive Disks (RAID) project, which led to high-performance storage systems from many companies. These projects earned three dissertation awards from the ACM. His current research interests are in building novel microprocessors using Intelligent DRAM (IRAM) and he currently consults for Sun, where he holds the title of Chief Scientist of the Network Attached Storage Division.
John L. Hennessy teaches computer architecture at Stanford University, where he has been a member of the faculty since 1977. He is currently Dean of the School of Engineering and the Frederick Emmons Terman Professor of Engineering. Hennessy is a fellowof the IEEE and ACM, a member of the National Academy of Engineering, and a fellow of the American Academy of Arts and Sciences. He received the 1994 IEEE Piore Award for his contributions to the development of RISC technology.
Hennessy's original research group at Stanford developed several of the techniques now in commercial use for optimizing compilers. In 1981, he started the MIPS project at Stanford with a handful of graduate students. After completing the project in 1984, he took a one-year leave from the university to co-found MIPS Computer Systems, which developed one of the first commercial RISC microprocessors. After being acquired by Silicon Graphics in 1991, MIPS Technologies became an independent company in 1998, focusing on microprocessors for the embedded marketplace. As of 1998, over 100 million MIPS microprocessors have been shipped in devices ranging from video games and palmtop computers to laser printers and network switches. Hennessy's recent research at Stanford focuses on the area of designing and exploiting multiprocessors. Recently, he has been involved in the development of the DASH multiprocessor architecture, the first distributed shared-memory multiprocessors supporting cache coherency, and the basis for several commercial multiprocessor designs.
