Joel S. Emer (born March 2, 1954)

MIT,[3] and was formerly an Intel Fellow.[4] He was the 2009 recipient of the Eckert–Mauchly Award.[4]

Early life and education

Born March 2, 1954,

.

Career

His first job immediately after graduation was at Digital Equipment Corporation where he initially worked on VAX performance evaluation and then on Alpha performance evaluation. As a consequence of his performance evaluation work, he became a pioneer in the quantitative approach to computer architecture.

He contributed a variety of research and advanced development ideas that were incorporated into various VAX and Alpha processor designs,[5] In conjunction with the development and application of various performance analysis techniques.

He worked at Compaq and Digital Equipment Corporation.[3] He subsequently worked at Intel, where he was Director of Microarchitecture Research,[5] out of the Massachusetts Microprocessor Design Center (MMDC).[6] He was named an Intel Fellow in 2001.[6]

He is well known, along with his co-author Douglas W. Clark, for a seminal paper on the quantitative analysis of processor architectures,

MIPS instead of 1 MIPS as was previously claimed by DEC. That result helped popularize what Clark called the iron law of processor performance that related cycles per instruction (CPI), frequency and number of instructions to computer performance
.

Emer has also contributed to simultaneous multithreading (SMT),[8] memory dependence prediction via store sets, and soft error analysis, and led the development of the Asim simulator.

He was the 2009 recipient of the Eckert–Mauchly Award,[4] for lifetime contributions in computer architecture.[3] In 2020, Emer was elected as a member into the National Academy of Engineering for quantitative analysis of computer architecture and its application to architectural innovation in commercial microprocessors.

He is currently a researcher at

MIT.[3][5]
