NEUROMORPHIC EVENT-DRIVEN NEURAL COMPUTING ARCHITECTURE IN A SCALABLE NEURAL NETWORK

摘要

An event-driven neural network includes a plurality of interconnected core circuits is provided. Each core circuit includes an electronic synapse array has multiple digital synapses interconnecting a plurality of digital electronic neurons. A synapse interconnects an axon of a pre-synaptic neuron with a dendrite of a post-synaptic neuron. A neuron integrates input spikes and generates a spike event in response to the integrated input spikes exceeding a threshold. Each core circuit also has a scheduler that receives a spike event and delivers the spike event to a selected axon in the synapse array based on a schedule for deterministic event delivery.

1. A method, comprising:
maintaining an array of multiple neurons, wherein the array includes multiple rows and multiple columns, and each row and each column of the array has a corresponding row serving module and a corresponding column serving module, respectively; and utilizing a distributed mutual exclusion protocol to adaptively control access of one or more spiking neurons of the multiple neurons to an output bus based rate of spikes generated by the multiple neurons.
