Patent ID: 8909576

Claim:
A neural network, comprising: a plurality of interconnected core circuits, each core circuit comprising: an electronic synapse array comprising multiple digital synapses interconnecting a plurality of digital electronic neurons, wherein each synapse interconnects an axon of a pre-synaptic neuron with a dendrite of a post-synaptic neuron, wherein each neuron integrates input spikes and generates a spike event in response to the integrated input spikes exceeding a potentiation threshold, and wherein each spike event includes a corresponding timestamp indicating generation of the spike event; and a scheduler that receives one or more spike events targeting one or more axons in the synapse array, and selectively imposes a delay on the spike events received before delivering the spike events to the axons, wherein, for each spike event received, the scheduler delivers the spike event to a selected axon in the synapse array based on a schedule for deterministic event delivery and a corresponding timestamp of the spike event.
