An On-Chip and Inter-Chip Communications Network for the SpiNNaker Massively-Parallel Neural Net Simulator

SpiNNaker is a scalable, multichip system designed for the purpose of real-time modelling of spiking neurons with an efficient multicast communications infrastructure inspired by neurobiology. SpiNNaker uses a GALS packet-switched network to emulate the very high connectivity of biological systems. This paper presents the on-chip and inter-chip communications network for SpiNNaker.
