Abstract:

A recognition system comprises at least two field-programmable logic array devices connected to a common vector-input port of an array of a zero-instruction-set computers. Each field-programmable logic array device is configured to preprocess data from different respective media inputs and provide feature extraction vectors to the common vector-input port. Neural networks within the zero-instruction-set computer recognize the input patterns by comparing in parallel their vectors with those stored in each neural network cell. A variety of recognition jobs are made possible by changing the programming on-the-fly of the field-programmable logic array devices to suit each new job.
