RED Semicondutor - Luke Leighton

Luke Leighton

Chief Technology Officer

Luke – inventor of Vector+1 and SVP64 instruction set and microprocessor architectures – has been a career-long advocate of open-source as the key enabler to overcoming limitations of corporate CPU architectures. He has worked on projects that demanded processing capabilities beyond those commercially available, and formed Libre-SOC to pioneer the development of a new open-source computing architecture where he is the majority contributor and curator of its IP and knowhow. Intent on delivering his innovative processing solution to major global markets, he joined David Calderwood in founding RED Semiconductor to commercially exploit his invention.
