Spiking Neural Networks (SNNs)

Neuromorphic processing for ultra-low power, real-time intelligence.

Advantages

Why SNNs?

AI That Works Like a Brain

Conventional AI at the edge is hitting a wall: power budgets, latency, and cloud dependence choke real-world deployments. Sensors capture rich signals, but silicon can’t keep up efficiently. Innatera’s neuromorphic Pulsar chip removes this bottleneck, delivering brain-inspired, event-driven intelligence directly at the sensor, where fast decisions actually need to happen.

The Spiking Neural Network Advantage

Ultra-low power operation enabling continuous sensing in micro- and nano-watt ranges
Real-time responsiveness with inherently low processing latency
Privacy by design through fully on-device data processing
Compact and scalable architectures optimized for embedded systems
Robust, adaptive performance resilient to noise and sparse signal activity

Benefits

Where our technology
makes a difference

Ultra-low power

Innatera’s Spiking Neural Processors deliver up to 500x lower energy than conventional edge AI, enabling truly always-on sensing in battery devices.

Instant response time

Innatera’s event-driven SNNs react up to 100x – Lower latency vs traditional pipelines, turning raw sensor spikes into decisions in real time.

No cloud

Innatera’s local intelligence drastically cuts radio and cloud usage, extending battery life by orders of magnitude and keeping data private on-device.

Developer-friendly SDK

Talamo SDK lets developers import existing models, tune SNNs, and deploy to Pulsar using standard Python tools and workflows.

Innatera Spiking Neural Processors

Event-driven Spiking Neural Networks (SNNs): neurons fire on changes; timing carries information

“Microwatt power levels” for always-on sensing on Pulsar

Sub-millisecond responsiveness

Up to 500× lower energy and up to 100× lower latency vs deep neural networks on mainstream digital hardware

Designed for real-time, on-device inference; reduces cloud dependency by processing only when needed

SNN engine + RISC-V MCU; hybrid support for SNN, CNN acceleration, and DSP

Strong fit (wake-on-event, low energy between events)

Local processing → less data sent to cloud by design

Conventional CNNs on mainstream digital hardware

Frame/clock-driven numerical operations (dense MACs over tensors)

Typically higher and continuous compute even when inputs are uninformative

Often higher latency; may rely on batching or cloud offload

Baseline for comparison: energy/latency depend on platform and model size

More likely to rely on cloud or higher-end SoCs for heavy workloads

CNN accelerators/NPUs or general GPUs/CPUs optimized for dense CNN ops

Always-on possible but usually at significantly higher energy budgets

More likely to transmit or process off-device when constrained

Data Journey

From Signal to Spike to Action

01 Data Capture / Sensing

Real-world signals are continuously captured from sensors, forming the foundation for intelligent, event-driven processing.

02 Encoding: Translating Signals into Spikes

Raw sensor data converts into temporal spike patterns, preserving timing and reducing unnecessary information flow.

03 Spiking Neural Processing

Event-driven SNNs analyze spikes in real time, extracting meaningful patterns with ultra-efficient compute.

04 Decoding / Actionable Output

Processed signals translate into decisions, classifications, or triggers directly at the sensor edge.

05 Feedback & Adaptation

Systems register responses over time, and can enable adaptive behavior and smarter edge intelligence in the future.

Real-Life Use Cases

Human Presence Detection

Instant awareness, zero privacy trade-offs. Spiking neural processors detect human presence in real time, locally and privately, enabling smarter buildings, safer devices, and always-on sensing at microwatt power.

Gesture and Motion Recognition

Touchless control, anywhere. SNNs interpret subtle gestures and motion directly on-device, unlocking intuitive interfaces for wearables, consumer electronics, and industrial systems—without heavy compute or the cloud.

Audio Scene Recognition and Anomaly Detection

Always listening, only when needed. Event-driven spiking chips recognize keywords or unusual sounds at the edge, reacting instantly while consuming ultra-low power and preserving user privacy.

And much more.
