COMMUNICATING POSTSYNAPTIC NEURON FIRES TO NEUROMORPHIC CORES

摘要

A system for communicating postsynaptic neuron states. The system includes a first neuromorphic core and a second neuromorphic core. The first neuromorphic core includes a first array of synaptic memory cells and postsynaptic neuron circuits. Each of the postsynaptic neuron circuits is coupled to a row of synaptic memory cells in the first array of synaptic memory cells. Each of the postsynaptic neuron circuits is configured to fire when voltage sensed from the row of synaptic memory cells exceeds a threshold. The second neuromorphic core includes a second array of synaptic memory cells. A neuron bus is configured to serially transmit indications of a postsynaptic neuron circuit fire from the first neuromorphic core to the second neuromorphic core.

1. A method for communicating postsynaptic neuron states to a neuromorphic core, the method comprising:
storing, in a first transmit buffer, indications of a postsynaptic neuron circuit fire from postsynaptic neuron circuits in a first neuromorphic core, each of the postsynaptic neuron circuits being coupled to a plurality of synaptic memory cells, the indications of postsynaptic neuron circuit fire identifying which of the postsynaptic neuron circuits fired; serially shifting the indications of postsynaptic neuron circuit fire to a neuron bus; receiving the indications of postsynaptic neuron circuit fire from the neuron bus at a plurality of presynaptic neuron circuits in a second neuromorphic core.
