[edit] Background

He earned his Bachelor's degree in electrical engineering from Villanova University, and his Master's degree and Ph.D. in computer science from the State University of New York at Stony Brook.

Hennessy became a Stanford faculty member in 1977. In 1984, he used his sabbatical year to found MIPS Computer Systems Inc. to commercialize his research in RISC processors. In 1987, he became the Willard and Inez Kerr Bell Endowed Professor of Electrical Engineering and Computer Science.

Hennessy served as director of Stanford's Computer System Laboratory (1989-1993), a research center run by Stanford's Electrical Engineering and Computer Science departments. He was chair of the Department of Computer Science (1994-1996) and Dean of the School of Engineering (1996-1999).

In 1999, Stanford President Gerhard Casper appointed Hennessy to succeed Condoleezza Rice as Provost of Stanford University. When Casper stepped down to focus on teaching in 2000, the Stanford Board of Trustees named Hennessy to succeed Casper as president. As Stanford's president, Hennessy earns an annual salary of $566,581.

In 1997, he was inducted as a Fellow of the Association for Computing Machinery, ACM.

Hennseey joined the board of Google, in exchange for 65,000 shares of the company; at the time of Google's IPO, his shares were worth over $7 million.^{[citation needed]} He is also a board member of Cisco Systems, Inc.^[1], Atheros Communications,^[2] and the Daniel Pearl Foundation.^[3]

[edit] Research

Hennessy has a history of strong interest and involvement in college-level computer education. He co-authored, with David A. Patterson, two well-known books on computer architecture, Computer Organization and Design: the Hardware/Software Interface and Computer Architecture: A Quantitative Approach, which introduced the DLX RISC architecture. They have been widely used as textbooks for graduate and undergraduate courses since 1990.^{[citation needed]}

Hennessy also contributed to updating Donald Knuth's MIX processor to the MMIX. Both are model computers used in Knuth's classic series, The Art of Computer Programming. MMIX is Knuth's DLX equivalent.
