Sophie Wilson is an English computer scientist, who helped design the BBC Micro and 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 Micro, including the BBC BASIC programming language whose development she led for the next 15 years. 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.
