Spiking Neural Network inference on FPGAs with hls4ml

arXiv:2606.10008v1 Announce Type: cross Abstract: Spiking Neural Networks (SNNs) provide a naturally temporal machine-learning framework. Their neurons maintain an internal state and propagate information through discrete spikes, enabling low-latency temporal inference. Although SNNs are often associated with asynchronous neuromorphic processors, many scientific real-time inference systems rely on conventional synchronous field-programmable gate arrays (FPGAs) and high-level synthesis (HLS) workflows. In this paper we present an extension of hls4ml that enables clock-driven deployment of SNNs

Why this matters
Why now

The increasing demand for efficient AI inference at the edge and the natural temporal advantages of SNNs are pushing for practical deployment solutions, making this integration timely.

Why it’s important

This development enables more efficient and low-latency AI inference on conventional hardware, broadening the applicability of sophisticated AI models in real-time embedded systems.

What changes

SNNs can now be more readily deployed on widely available synchronous FPGAs using existing high-level synthesis workflows, bridging a gap between neuromorphic architectures and conventional hardware.

Second-order effects
Direct

SNNs become a more viable option for embedded and edge AI applications requiring low latency and energy efficiency.

Second

Increased adoption of SNNs could drive further research and development in SNN algorithms and hardware co-design, potentially leading to more specialized, energy-efficient AI chips.

Third

The enhanced capability for on-device AI inference might accelerate the development of autonomous systems with greater real-time intelligence, impacting sectors like robotics, IoT, and defense.
