Scientists at International Business Machines (IBM) have developed a new type of computer chip, inspired by the architecture of the human brain, which uses less power than a hearing aid, is roughly the size of a postage stamp, and could potentially surpass modern supercomputers in terms of calculation capability.
The chip, named TrueNorth, attempts to mimic the way the human brain is able to recognize patterns, relying on densely interconnected webs of transistors, similar to that of the brain’s neural networks. The electronic “neurons” in the chip are able to singal each other when a type of data passes a certain threshold. By working in parallel, the neurons are able to organize the data into patterns.
This process enables the chip to recognize things that humans can do subconsciously, but that modern computers and robots struggle with. The chip could help computers and robots overcome some of the biggest issues they currently face which are limiting their potential. Known as a “neurosynaptic” chip, this breakthrough could potentially blow open the doors to innumerable computing possibilities.
“The TrueNorth chip is like the first transistor,” said Terrence J. Sejnowski, director of the Salk Institute’s Computational Neurobiology Laboratory. “It will take many generations before it can compete, but when it does, it will be a scalable architecture that can be delivered to cellphones, something that Yann’s G.P.U.s will never be able to do.”
