Arm engineering veteran joins ‘reversible computing’ startup
Andrew Sloss, a veteran engineer who ended his 25 years at Arm as senior principal research engineer, has joined a UK startup called Vaire Computing Ltd.
Vaire Computing, headquartered in London, was founded September 2021 by Rodolfo Rosini with the goal of working on “reversible computing,” something that Rosini claims could deliver logic circuits that consume near-zero energy.
On his Linkedin page Sloss describes the mission of the company as being to create “physics-aware architectures with behavioural support for existing software.” He continues: “It comes down to making the logic aware of the physics from transistors upwards.” Sloss added: “Physics gives us a huge bag of tricks we haven’t used in the architecture space.”
This suggests that Vaire Computing is considering something not dissimilar to the thermodynamics-based probabilistic-AI of US startup Normal Computing Inc. (see Ex-Google engineers’ probabilistic, AI startup raises seed funding). The aim would be to develop processors that can provide orders of magnitude improvement in thermal efficiency. Wasteful energy consumption is rapidly becoming the number one challenge in high-performance semiconductor development.
To help the company during its startup phase Vaire Computing has joined the incubator organization Silicon Catalyst UK.
