Ross Freeman (1944 or 1948–1989), was an American electrical engineer and inventor, and co-founder of the leading FPGA developer Xilinx. == Early life and education == Freeman was born in upper Engadine, Michigan on July 26, 1948 〔 Ross's first Cousin Carol Comfort Dannenberg 〕 〔 Ethel Freeman -Ross's Mother 〕 Freeman earned a BS degree in physics from Michigan State University in 1969 and a master’s from University of Illinois in 1971.〔 He worked in the Peace Corps for several years, then went to Teletype Corporation to design a custom PMOS circuit.〔 == Founding of Xilinx == Ross postulated that because of Moore's Law, transistors would be getting less expensive each year, making customizable programmable chips affordable. The idea was "far out" at the time, but the company and technology grew quickly, eventually catching the attention of new-found competitors in what is now a mature industry.〔(Xilinx History Page )〕〔Funding Universe. “(Xilinx, Inc. )” Retrieved January 15, 2009.〕 With Bernard Vonderschmitt and James V Barnett II Freeman co-founded Xilinx in 1984, and a year later invented the first Field Programmable Gate Array. Freeman's invention - patent 4,870,302 - is a computer chip full of 'open gates' that engineers can reprogram as much as needed to add new functionality, adapt to changing standards or specifications and make last minute design changes.〔Company Release, "(Xilinx Co-Founder Ross Freeman Honored as 2009 National Inventors Hall of Fame Inductee for Invention of FPGA )".
