Joel Emer

Joel Emer Springer ( born March 2, 1954) is an American computer engineer.

Emer studied electrical engineering at Purdue University with a bachelor 's degree in 1974 ( with honors ) and master's degree in 1975. 1979 he received his doctorate at the University of Illinois at Edward Davidson. He then went to DEC.

He researched ( 64 bit processors for servers ) to the VAX architecture and the architecture of future Alpha processors at DEC and continued this even when takeover by Compaq. In 2001 he came to Intel, as they began a collaboration with Compaq, when Intel took over the microprocessor research. He is Intel Fellow and Director of Research at microarchitecture ( Microachitecture Research).

He became known as one of the pioneers in the quantitative measurement and modeling of processor performance in his time at DEC (and thus the quantitative access to computer architecture). In an influential work with Douglas Clark, he showed at that time that the VAX-11/780 with 0.5 MIPS had only half as much power as DEC before claiming tete ..

Emer also conducted research on simultaneous multithreading ( SMT), pipeline organization in processors, cache memory design, memory dependence, influence of " soft errors " on the architecture.

In 2009 he received the Eckert - Mauchly Award. He is a Fellow of IEEE and a Fellow of the Association for Computing Machinery (ACM ).
