The Deferred Event Model for Hardware-Oriented Spiking
... Abstract. Real-time modelling of large neural systems places critical demands on the processing system’s dynamic model. With spiking neural networks it is convenient to abstract each spike to a point event. In addition to the representational simplification, the event model confers the ability to de ...
