Yale Electrical Engineering Seminar Series
Speaker: Dr. Ivan Sutherland
Portland State University
Microelectronics and Computer Science
Host: Prof. Rajit Manohar, Dept. of EE and Computer Science, Yale Univ.
Abstract: Microelectronics has overturned the relative cost of logic and communication, disrupting the foundations of Computer Science. We still count operations. We still think sequentially. We too often ignore wires. We can do better. “Scientists” who study computers should recognize the actual costs imposed on our machines by the silicon chips we use to build them.
Ivan will explore Ronken’s Link and Joint model of self-time systems. It not only simplifies thinking about of self-timing but also conforms to Physics. He will describe Weaver, an 8x8 crossbar experiment, and HexNet, an on-chip network now in planning. Both are based on the Link and Joint model.
Bio: Ivan Sutherland is a long-time proponent of Self-Timed systems. His 1988 Turing Award paper, Micropipelines, inspired widespread interest in the topic. He holds a few notable awards and honorary degrees as well as membership in both the National Academy of Engineering and the National Academy of Science. He is sometimes called the “father of computer graphics” for his 1963 PhD work in that field, but her prefers the nickname “god father of virtual reality” that was recently awarded him for having built the first very crude head-mounted display in 1968. Rather than not planning to retire he plans, like Fred Brooks, not to retire. Ivan and his wife Marly Roncken run the Asynchronous Research Center (ARC) at Portland State University in Oregon.
