Sophie Wilson

Sophie Wilson is the principal designer of the original ARM instruction set architecture, developed at Acorn Computers in 1983 to 1985. A self-taught programmer who joined Acorn in 1978, Wilson designed the ARM instruction set, the fundamental language that ARM processors execute, drawing on RISC research principles from Berkeley and Stanford and combining them with practical engineering constraints imposed by Acorn's budget and manufacturing capabilities. The elegance and simplicity of the instruction set Wilson designed proved to be the enduring foundation of ARM's competitive advantage.

Sophie Wilson, along with Steve Furber, designed the original ARM processor at Acorn Computers in 1983 to 1985. Wilson was responsible for the ARM instruction set architecture, a contribution that makes her one of the most consequentially influential chip architects in computing history, even as her role is less widely known outside technical communities than the commercial story of the companies that commercialized her design. Wilson became a Fellow of the Royal Society and a Fellow of the Royal Academy of Engineering, both among the United Kingdom's highest scientific honors. After the formation of Arm Ltd., Wilson did not join the new company directly, instead remaining at Acorn before the company's eventual dissolution. She joined Broadcom's Cambridge design center, where she has continued to work on processor and network chip design. Wilson was awarded a CBE in 2019 for services to the technology industry.

Sophie Wilson was born in 1957 in Leeds. Education: Selwyn College.
