About the Event

With the "end" of Moore's Law, there is renewed interest in multi-chip modules, which provide a way to build large systems with relatively small chips built on disparate technologies. To make this practical, signaling on an MCM must be extremely pin- and energy-efficient. This talk describes some recent work at Nvidia to build such links, resulting in chip-to-chip signaling that is as energy efficient as on-chip signaling.


John Poulton received the B.S. degree from Virginia Polytechnic Institute and State University, Blacksburg, in 1967, the M.S. degree from the State University of New York, Stony Brook, in 1969, and the Ph.D. degree from the University of North Carolina, Chapel Hill (UNCCH) in 1980, all in physics. >From 1981 to 1999, he was a researcher with the Department of Computer Science, UNCCH, where from 1995 he held the rank of Research Professor. He performed research on VLSI-based architectures for graphics and imaging and was a pricipal contributor to the design and construction of several experimental high-performance graphics systems. From 1999 to 2003 he was Chief Engineer with Velio Communications, where he developed gigabit chip-to-chip signaling systems. From 2003 to 2009 he was a Technical Director with Rambus, Inc., Chapel Hill, where he led an effort to build power-efficient multi-gigabit I/O systems. Presently he is Senior Scientest at NVIDIA, Inc., Durham, NC, and is an IEEE Fellow.
