Joel Emer
Joel Springer Emer (born March 2, 1954 ) is an American computer engineer.
Emer studied electrical engineering at Purdue University with a bachelor's degree in 1974 (with top marks) and a master's degree in 1975. In 1979 he received his doctorate from the University of Illinois under Edward Davidson . He then went to DEC .
He researched the VAX architecture and the architecture of future alpha processors at DEC (64 bit processors for servers) and continued this with the takeover by Compaq . He came to Intel in 2001 when they started a collaboration with Compaq, where Intel took over microprocessor research. He is an Intel Fellow and Head of Microarchitecture Research.
He became known as one of the pioneers in the quantitative measurement and modeling of processor performance during his time at DEC (and thus the quantitative access to computer architecture). In an influential work with Douglas Clark, he showed that the VAX-11/780 with 0.5 MIPS only had half as much power as DEC previously claimed. Emer also researched Simultaneous Multithreading (SMT), pipeline organization in processors, cache memory design, memory dependence, and the influence of " soft errors " on the architecture.
In 2009 he received the Eckert-Mauchly Award . He is an IEEE Fellow and a Fellow of the Association for Computing Machinery (ACM). In 2020 Emer was elected to the National Academy of Engineering .
