A 20 Tera-CPS analog neural network board

Demonstrates an analog neural network board which integrates 18 interconnected neural network chips. The board realizes a fully feedback connection network consisting of 1,008 neurons and 1,016,064 synapses. The speed performance of the neural network is 20/spl times/10/sup 12/ connections per second (CPS) and 500/spl times/10/sup 9/ connections update per second (CUPS).
