NeuroRing: Scaling Spiking Neural Networks via Multi-FPGA Bidirectional Ring Topologies and Stream-Dataflow Architectures

Artur Podobas, Muhammad Ihsan Al Hafiz

A bidirectional ring topology and stream-dataflow architecture on FPGAs enables scalable faster-than-real-time execution of large spiking neural networks while preserving activity statistics.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

NeuroRing preserves the key activity statistics of the NEST reference model, achieves faster-than-real-time execution of the full-scale cortical microcircuit with a real-time factor (RTF) of 0.83, exhibits meaningful strong and weak scaling, and provides competitive energy efficiency on two programmable FPGAs.

C2weakest assumption

That the bidirectional ring topology and stream-dataflow architecture will continue to avoid communication bottlenecks and synchronization overhead when scaled beyond the evaluated two-FPGA configuration or to networks with different spike sparsity patterns.

C3one line summary

NeuroRing delivers a modular multi-FPGA accelerator for spiking neural networks that achieves real-time factor 0.83 on the full cortical microcircuit while preserving NEST activity statistics and showing scaling behavior.
