Brainy IBM Chip Packs One Million Neuron Punch

Aug 7, 2014 |

IBM researchers have developed a super-efficient chip inspired by the functioning of the human brain. Named TrueNorth, the chip features 5.4 billion transistors arranged in a network of 4,096 neurosynaptic cores, yielding the equivalent of one million neurons and 256 million synapses. Despite being one of the largest CMOS chips ever built, TrueNorth consumes just 70mW during Read more…

Is This the Exascale Breakthrough We’ve Been Waiting For?

Aug 6, 2014 |

An animated video, narrated by the inimitable Professor Heinz Wolff, popped up on YouTube last month, detailing a prototype optical processor with some remarkable claims. The company behind the effort, UK-based startup Optalysys, says it is on track to deliver exascale levels of processing power on a standard-sized desktop computer within the next few years.
