ABSTRACT:
A neural network has an array of interconnected processors, each processor operating either the pulse domain or spike domain. Each processor has (i) first inputs selectively coupled to other processors in the array of processors, each first input having an associated 1 bit DAC coupled to a summing node, (ii) second inputs selectively coupled to inputs of the neural network, the second inputs having current generators associated therewith coupled to said summing node, (iii) a filter/integrator for generating an analog signal corresponding to current arriving at the summing node, (iv) an optional nonlinear element coupled to the filter/integrator, and (v) an analog-to-pulse converter, if the processors operate in the pulse domain, or an analog-to-spike convertor, if the processors operate in the spike domain, for converting an analog signal output by the optional nonlinear element or by the filter/integrator to either the pulse domain or spike domain, and providing the converted analog signal as an unquantized pulse or spike domain signal at an output of the processor. The array of processors are selectively interconnected with either unquantized pulse domain or spike domain signals.
