Submission + - IBM 'TrueNorth' neuro-synaptic chip promises huge changes -- eventually
JakartaDean writes: Each chip contains 1.8 billion transistors but runs on 70 milliwatts. The chips are designed to behave like neurons—the basic building blocks of biological brains. Modha, the head of IBM's cognitive computing group, says the system (24 connected chips) in front of us spans 48 million of these artificial nerve cells, roughly the number of neurons packed into the head of a rodent.
Whereas conventional chips are wired to execute particular “instructions,” the TrueNorth juggles “spikes,” much simpler pieces of information analogous to the pulses of electricity in the brain. Spikes, for instance, can show the changes in someone’s voice as they speak—or changes in color from pixel to pixel in a photo. “You can think of it as a one-bit message sent from one neuron to another.” says one of the chip’s chief designers.
