The original purpose of the original ARM chip was to drive the Acorn Archimedes desktop computer. While they were aiming to design a power efficient device, the power consumption accidentally turned out to be far lower than intended, which has been a big reason for ARM's continued success in many uses.
- w0mbat 7y agoThe team's design goal was 1 watt, but the chip ended up needing only a tenth of a watt. In fact on the original testbed they forgot to wire up the power lines to the chip, but the processor still worked, appearing to be running on no power at all! It turned out that it needed so little power that it could run on just the leakage from the data lines. https://www.theregister.co.uk/Print/2012/05/03/unsung_heroes_of_tech_arm_creators_sophie_wilson_and_steve_furber/ https://www.theregister.co.uk/Print/2012/05/03/unsung_heroes...
