Researchers Thursday unveiled a powerful new postage-stamp size chip delivering supercomputer performance using a process that mimics the human brain. The researchers from IBM, Cornell Tech and collaborators from around the world said they took an entirely new approach in design compared with previous computer architecture, moving toward a system called cognitive computing. We have taken inspiration from the cerebral cortex to design this chip, said IBM chief scientist for brain-inspired computing, Dharmendra Modha, referring to the command center of the brain. The new chip dubbed TrueNorth works to mimic the right brain functions of sensory processing — responding to sights, smells and information from the environment to learn to respond in different situations, Modha said.
