GLOBALLY ASYNCHRONOUS AND LOCALLY SYNCHRONOUS (GALS) NEUROMORPHIC NETWORK

摘要

Embodiments of the invention relate to a globally asynchronous and locally synchronous neuromorphic network. One embodiment comprises generating a synchronization signal that is distributed to a plurality of neural core circuits. In response to the synchronization signal, in at least one core circuit, incoming spike events maintained by said at least one core circuit are processed to generate an outgoing spike event. Spike events are asynchronously communicated between the core circuits via a routing fabric comprising multiple asynchronous routers.

1. A method comprising:
at a scheduler for a core circuit of a plurality of hardware core circuits:
receiving one or more address-event packets;decoding each of the one or more address-event packets;storing one or more spikes decoded from the one or more address-event packets into a memory of the scheduler, wherein each spike is scheduled for delivery in a future time step; andin response to receiving a signal indicating occurrence of a time step:
reading, from the memory, one or more spikes scheduled for delivery in the time step; andsending the one or more spikes scheduled for delivery in the time step to a router connected to the core circuit for delivery to one or more target axons.
