Sophie Wilson
Sophie was born in Leeds, England, in 1957.She studied computer science at the University of Cambridge. She worked at Acorn Computers in the 1980s.
She designed the original instruction set for the ARM chip in just a few days.. ARM stands for Acorn RISC Machine. The design uses very little power and runs very fast
Billions of devices use ARM processors.. Most smartphones and tablets rely on her chip design. Routers, gaming consoles, and smart devices also use ARM
Without her, so much of todays tech would not be possible.

There was a Docudrama about the battle between Clive Sinclair and Acorn computers in the 80's She played a huge part in designing the BBC Micro computer. An actor plays Sophie (Roger then) Wilson, Although, Sophie did appear at the end as a a barmaid at 1:19:55 in the drama.

It is an interesting and fun story.
Sophie is a giant in the computing world there are many interviews with her.
This is the latest one I found

Í'm a great fan ...
... of the BBC Micro. It was my second home computer (the first was a copy of of the TRS80 called a Video Genie) and I was very impressed with its architecture. I built a second processor board using a Motorola 6809 running an OS called Flex which we used at work and enabled me to write S/W at home. I'm doubly impressed because I'm very much not a fan of Clive Sinclair for a wealth of reasons.
I regret to confess that I've never heard of Sophie Wilson but I'll certainly follow up the links you've provided and correct that. I'm long retired and extremely rusty technically but my first involvement with computers was back in 1961 (I was 21) when I had to 'Google' the local library to find out just what they were before my interview, so a little more background into how we ended where we are now is welcome in my dotage.
Trans People Helped Mold The World...
So just an FYI, you inspired me to start a series called "Trans People Helped Mold The World" and my first entry is on Sophie Wilson. I have plans done a post on Wendy Carlos in the past, but plan to add her to this series as well as others. Thank you for the inspiration!

Sophie is one of my heroines
Thanks for bringing this to people's attention. The woman who designed the Acorn BBC Micro (my first computer...) , and was lumped with creating BBC Basic to work on it too. Oh yeah, and created the chip archicture in all our phones. And beat that t****er Clive Sinclair, he of the C5 fame.Talking 'bout my generation (ish).
