The BBC was made by a company called Acorn (where Wilson worked), and after the BBC they wanted to go 32-bit but were unhappy with the Motorola offerings of the time - so they designed their own brilliant low power processor for their “Archimedes” machine.

They later spun the processor division off, calling it “Acorn RISC Machines”, where Sophie Wilson still works - except, it was shortened to the acronym, ARM. Yes, that ARM.
