Sophie Mary Wilson CBE FRS FREng DistFBCS (born Roger Wilson; June 1957) is an English computer scientist, a co-designer of the Instruction Set for the ARM architecture.
Wilson first designed a microcomputer during a break from studies at Selwyn College, Cambridge. She subsequently joined Acorn Computers and was instrumental in designing the BBC Microcomputer, including the BBC BASIC programming language. She first began designing the ARM reduced instruction set computer (RISC) in 1983, which entered production two years later. It became popular in embedded systems and is now the most widely used processor architecture in smartphones. In 2011, she was listed in Maximum PC as number 8 in an article titled "The 15 Most Important Women in Tech History". She was made a Commander of the British Empire in 2019.
Early life and education
Wilson was born in 1957 and brought up in Leeds, Yorkshire. Her parents were both teachers, with her father specialising in English and her mother in physics. From 1975, she studied computer science and the Mathematical Tripos at Selwyn College, University of Cambridge and was a member of their Microprocessor society.
Career
In an Easter break from university, Wilson designed a microcomputer with a MOS Technology 6502 microprocessor, inspired by the earlier MK14, which was used to electronically control feed for cows.
In 1978, she joined Acorn Computers Ltd, after designing a device to prevent cigarette lighter sparks triggering payouts on fruit machines. Wilson's computer design was used by Chris Curry and Hermann Hauser to build the Acorn Micro-Computer, the first of a long line of computers sold by the company.
In July 1981, Wilson extended the Acorn Atom's BASIC programming language dialect into an improved version for the Acorn Proton, a microcomputer that enabled Acorn to win the contract with the British Broadcasting Corporation (BBC) for their ambitious computer education project. Hauser employed a deception, telling both Wilson and colleague Steve Furber that the other had agreed a prototype could be built within a week. Taking up the challenge, she designed the system including the circuit board and components from Monday to Wednesday, which required fast new DRAM integrated circuits to be sourced directly from Hitachi. By Thursday evening, a prototype had been built, but the software had bugs, requiring her to stay up all night and into Friday debugging. Wilson recalled watching the wedding of Prince Charles and Lady Diana Spencer on a small portable television while attempting to debug and re-solder the prototype. It was a success with the BBC, who awarded Acorn the contract. Along with Furber, Wilson was present backstage at the machine's first airing on television, in case any software fixes were required. She later described the event as "a unique moment in time when the public wanted to know how this stuff works and could be shown and taught how to programme."
The Proton became the BBC Micro and its version of BASIC, BBC BASIC had been developed by Wilson.
In October 1983, Wilson began designing the instruction set for one of the first reduced instruction set computer (RISC) processors, the Acorn RISC Machine (ARM). The ARM1 was delivered on 26 April 1985 and worked first time. This processor type was later to become one of the most successful IP cores – a licensed CPU core – and by 2012 was being used in 95% of smartphones.
Wilson designed Acorn Replay, the video architecture for Acorn machines. This included operating system extensions for video access, as well as the codecs, optimised to run high frame rate video on ARM CPUs from the ARM 2 onwards.
She was a non-executive director of the technology and games company Eidos plc, which bought and created Eidos Interactive, for the years following its flotation in 1990. She was a consultant to ARM Ltd when it was split off from Acorn in 1990.
Since the demise of Acorn Computers, Wilson has made a small number of public appearances to talk about work done there.
She was the Chief Architect of Broadcom's Firepath processor. Firepath has its history in Acorn Computers, which, after being renamed to Element 14, was broken up in an acquisition, with the Element 14 name being transferred to a new company, this company eventually being bought by Broadcom in 2000.
Wilson was listed in 2011 in Maximum PC as number 8 in an article titled "The 15 Most Important Women in Tech History".
Honours and awards
Wilson was awarded the Fellow Award by the Computer History Museum in California in 2012 "for her work, with Steve Furber, on the BBC Micro computer and the ARM processor architecture." In 2009, she was elected as a Fellow of the Royal Academy of Engineering and, in 2013, as a Fellow of the Royal Society. Wilson received the 2014 Lovie Lifetime Achievement Award in acknowledgement for her invention of the ARM processor. In 2016, she became an honorary fellow of her alma mater, Selwyn College, Cambridge. In 2020, she was honoured as a Distinguished Fellow of the British Computer Society.
Wilson was appointed Commander of the Order of the British Empire (CBE) in the 2019 Birthday Honours for services to computing.
In 2022 the Charles Stark Draper Prize for Engineering was awarded in Washington D.C. to David A. Patterson, John L. Hennessy, Stephen B. Furber, and Sophie M. Wilson for their "invention, development, and implementation" of the RISC chips.
Personal life
Wilson underwent gender reassignment surgery and transitioned from male to female in 1994. She enjoys photography and is involved in a local theatre group, where she is in charge of costumes and set pieces and has acted in a number of productions. She has also played a cameo role as a pub landlady in the BBC television drama Micro Men, in which a younger Wilson is played by Stefan Butler.
