The world’s largest neuromorphic supercomputer designed and built to work in the same way a human brain does has been fitted with its landmark one-millionth processor core and is being switched on for the first time.The newly formed million-processor-core ‘Spiking Neural Network Architecture’ or 'SpiNNaker' machine is capable of completing more than 200 million million actions per second, with each of its chips having 100 million transistors.
