description: >
The Arm Ethos-U NPUs are designed for IoT inference applications. The NPUs
can accelerate 8-bit and 16-bit integer quantized networks:
Transformer networks (U85 only)
Convolutional Neural Networks (CNN)
Recurrent Neural Networks (RNN)

Annotation
- Immediate include surface: `dt-bindings/interrupt-controller/irq.h`, `dt-bindings/interrupt-controller/arm-gic.h`, `dt-bindings/clock/imx93-clock.h`.
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
