Low-power chips to model a billion neurons | KurzweilAI
A miniature, massively parallel computer, powered by a million ARM processors, could produce the best brain simulations yet, Steve Furber suggests in IEEE Spectrum.
With traditional digital circuits, that would require a supercomputer that’s 1000 times as powerful as the best ones we have available today. And we’d need the output of an entire nuclear power plant to run it.
Fortunately, there are at least half a dozen projects dedicated to building brain models using specialized analog circuits that can model brain activity as fast as or even faster than it really occurs, and they consume a fraction of the power.
