I wrote for Wired about computer chips designed specifically for building neural networks:
Qualcomm is now preparing a line of computer chips that mimic the brain. Eventually, the chips could be used to power Siri or Google Now-style digital assistants, control robotic limbs, or pilot self-driving cars and autonomous drones, says Qualcomm director of product management Samir Kumar.
But don’t get too excited yet. The New York Times reported this week that Qualcomm plans to release a version of the chips in the coming year, and though that’s true, we won’t see any real hardware anytime soon. “We are going to be looking for a very small selection of partners to whom we’d make our hardware architecture available,” Kumar explains. “But it will just be an emulation of the architecture, not the chips themselves.”
Qualcomm calls the chips, which were first announced back in October, Zeroth, after the Isaac Asimov’s zeroth law of robotics: “A robot may not harm humanity, or, by inaction, allow humanity to come to harm.”
The Zeroth chips are based on a new architecture that radically departs from the architectures that have dominated computing for the past few decades. Instead, it mimics the structure of the human brain, which consists of billions of cells called neurons that work in tandem. Kumar explains that although the human brain does its processing much more slowly than digital computers, it’s able to complete certain types of calculations much more quickly and efficiently than a standard computer, because it can do many calculations at once.
Even the world’s largest supercomputers are able to use “only” one million processing cores at a time.
