The 40th anniversary of the Arm processor was celebrated at the UK's Centre for Computing History, reflecting on its immense impact. Initially developed by Acorn, the Arm chip worked successfully on its first power-up in 1985, thanks to a ten-person team led by innovators like Sophie Wilson. The chip marked a pivotal moment in computing, enabling low-power designs that would later power billions of devices. Despite a minor bug, the groundbreaking nature of the Arm architecture has reshaped technology and computing.
It did not say, 'Hello world, I am Arm,' laughed Wilson at the event. I think that's one of Hermann's apocryphal stories! But it did say Pi.
A ten-person team had spent 18 months working on the low-power RISC chip, and it had pretty much worked the first time. Famously, a problem with the board meant that a connected ammeter registered zero power consumption.
