# nsx-ethos-u-driver

<!-- nsx:facts -->
NSX integration of Arm's Ethos-U core driver. Wraps the upstream ethos-u-core-driver (vendored as plain files) with NSX build glue, CMSIS-based cache coherency hooks, a board-supplied IRQ shim, and inference begin/end probes. Runtime-agnostic — consumed by HeliaAOT, HeliaRT, TFLM applications, and bespoke C runtimes alike.

- Type: Library / service

## Add it to an app

```bash
nsx module add nsx-ethos-u-driver
```

## Capabilities

- npu
- ethos_u
- ethos_u55
- ethos_u65
- ethos_u85
- inference

## Use cases

- run Vela-compiled command streams on Ethos-U NPUs
- NPU IRQ wiring and cache-coherent invocation on Armv8.1-M hosts
- host-side begin/end probes for profiling (e.g. helia-profiler)

## Requires

- [`nsx-cmsis-core`](https://ambiqai.github.io/neuralspotx/modules/nsx-cmsis-core/)
- [`nsx-core`](https://ambiqai.github.io/neuralspotx/modules/nsx-core/)
- [`nsx-soc-hal`](https://ambiqai.github.io/neuralspotx/modules/nsx-soc-hal/)

## Optional dependencies
