A reconfigurable WSI neural network

Abstract
The solution presented consists of implementing the N neuron Hopfield network as a systolic square array made up of N/sup 2/ cells. Systolic arrays are well suited to wafer-scale integration (WSI). Inherent error tolerance of neural networks facilitates wafer design. However, a wafer-level reconfiguration is required to bypass faulty chips. The principle and the architecture of a switching element which provides a flexible wafer-level reconfiguration is described.
