Sophie Wilson – Insights on Inventions, Patents, and Patent Applications

Sophie Wilson is one of the key figures who revolutionized microprocessor technology. She co-developed the ARM processor that might be living inside your smartphones, tablets, computers, WiFi devices, or even the ABS in cars, etc. 

The success of this processor could be attributed to the fact that her company has shipped more than 160 billion ARM-based chips to date.

Though the story is four decades old, it still doesn’t fail to amaze the technology enthusiasts. Sophie was recruited to Acorn while she was still studying Computer Science at Cambridge University. While working at Acorn Sophie along with Steve Furber, she designed and implemented a prototype of the BBC Microcomputer within a week’s time. Their effort helped Acorn to bag the contract for the Computer Literacy Project from BBC. Sophie also designed the operating system as well as wrote and executed BBC BASIC for a succession of processors.

The processor (First Arm Processor) they developed excelled in energy-efficiency as it needed fewer transistors than other designs – making it ideal for mobile devices. The current day processor is 10000 times smaller than the first one according to Sophie herself.

The processor was a smash hit so much so that a generation of British schoolchildren grew up with Microcomputers (BBC Microcomputers) she designed in their classroom.

Thereafter, Sophie along with 6 other partners founded a new start-up company Element 14 in 1999 based on a SIMD LIW processor known as FirePath. Their idea was to use FirePath in the ADSL wired broadband market. 

Element 14 was later acquired by Broadcom in 2000. Currently, the Firepath processor is being sold by Broadcom for DSL and other applications. Sophie is presently working at Broadcom and has continuously been working on new ideas to make the microprocessor technology better.

Here is a lecture she gave on the future of microprocessors:

She also is an honorary fellow of the Computer History Museum and was a finalist in the 2013 European Inventor of the Year in the lifetime achievement category. Below is a list of honors and awards Wilson has received. Followed by it is a quick snapshot of her patent portfolio
