| ------ ArmNN for Android NNAPI supported operations ------ |
| |
| This release of ArmNN for Android supports use as a driver for the Android Neural Networks API. It implements the |
| android.hardware.neuralnetworks@1.0, android.hardware.neuralnetworks@1.1, android.hardware.neuralnetworks@1.2 and |
| android.hardware.neuralnetworks@1.3 |
| HAL interfaces. |
| |
| For more information on the Android Neural Networks API, see https://developer.android.com/ndk/guides/neuralnetworks/index.html |
| |
| For integration and usage documentation, please see README.md. |

| Where operations are not supported by the ArmNN Android NN Driver, the driver indicates this to the framework |
| appropriately and the framework implements those operations using a CPU implementation. |
| |
| NOTE: By convention, only those tensor types have been listed above, which are fully supported across all |
| ArmNN backends. |
| - FLOAT16 input tensors are partially supported on most HAL 1.2 operators on the GpuAcc and |
| CpuRef backends, however not on CpuAcc. |
