Joseph A. "Josh" Fisher is an American computer scientist. He is a Hewlett-Packard Senior Fellow. He worked at HP Labs from 1990 through 2006 in instruction-level parallelism and in custom embedded VLIW processors and their compilers. Fisher retired from active employment at HP in 2006.
As a professor at Yale University, he created and named VLIW Architectures and invented many of the fundamental technologies of ILP. In 1984, he started Multiflow Computer with two members of his Yale team. He won an NSF Presidential Young Investigator Award in 1984, was the 1987 Connecticut Eli Whitney Entrepreneur of the Year, and in 2003 received the ACM/IEEE Eckert-Mauchly Award.
Fisher coauthored Embedded Computing: A VLIW Approach to Architectures, Compilers and Tools, published in 2005 by Morgan Kaufmann/Elsevier. In 2013 CreateSpace Independent Publishing Platform released "Multiflow Computer: A Start-up Odyssey" written by Elizabeth Fisher, describing Fisher's contribution to building the VLIW-based Trace computer and business around it.
