David Money Harris Associate Professor of Engineering at Harvey Mudd College in Claremont, CA, holds a Ph.D. from Stanford University and S.B. and M.Eng. degrees from MIT. His research interests include CMOS VLSI design, microprocessors, and computer arithmetic. He holds a dozen patents, is the author of three other books in the field of digital design and three hiking guidebooks, and has designed chips at Sun Microsystems, Intel, Hewlett-Packard, and Evans & Sutherland. As owner of Harris Consulting, he serves regularly as an expert witness in patent litigation, addressing issues including claims construction, conception, ownership, and infringement analysis, validity and prior art, code…
