## Runtime Integration

An example runtime application is available in [examples/arm/executor_runner](https://github.com/pytorch/executorch/blob/main/examples/arm/executor_runner/), and the steps requried for building and deploying it on a FVP it is explained in the previously mentioned [Arm Ethos-U Backend Tutorial](https://docs.pytorch.org/executorch/stable/tutorial-arm-ethos-u.html).
An example runtime application is available in [examples/arm/executor_runner](https://github.com/pytorch/executorch/blob/main/examples/arm/executor_runner/), and the steps requried for building and deploying it on a FVP it is explained in the previously mentioned [Arm Ethos-U Backend Tutorial](tutorials/ethos-u-getting-started.md).
The example application is recommended to use for testing basic functionality of your lowered models, as well as a starting point for developing runtime integrations for your own targets.
For an in-depth explanation of the architecture of the executor_runner and the steps required for doing such an integration, please refer to [Ethos-U porting guide](https://github.com/pytorch/executorch/blob/main/examples/arm/ethos-u-porting-guide.md).
