IBM researchers make a chip full of artificial neurons

The new processor, which the team is calling TrueNorth, takes a radically different approach. Its 5.4 billion transistors include over 4,000 individual cores, each of which contain a collection of circuitry that behaves like a set of neurons. Each core has over 100,000 bits of memory, which store things like the neuron's state, the addresses of the neurons it receives signals from, and the addresses of the neurons it sends signals to.
They found that TrueNorth cut energy use by 176,000-fold compared to a traditional processor and by a factor of over 700 compared to specialized hardware designed to host neural networks.
"by tiling multiple TrueNorth chips, creating systems with hundreds of thousands of cores, hundreds of millions of neurons, and hundreds of billion of synapses."
