IVGCVSW-1806 Refactored Android-NN-Driver, added common "getCapabilities", "getSupportedOperations" and "prepareModel" implementations * Added common base ArmnnDriverImpl class * Added common template implementation of the driver's "getCapabilities", "getSupportedOperations" and "prepareModel" methods * Refactored ArmnnPreparedModel and RequestThread to support HAL v1.1 models * Moved "getStatus" to the common base class, as it is shared by both HAL implementations * Refactored the code where necessary Change-Id: I747334730026d63b4002662523fb93608f67c899
This directory contains the ArmNN driver for the Android Neural Networks API, implementing the android.hardware.neuralnetworks@1.0 HAL and android.hardware.neuralnetworks@1.1 HAL.

directory in the Android image. To update the build environment, add to the contents of the variable PRODUCT_PACKAGES
within the device-specific makefile that is located in the <ANDROID_ROOT>/device/<manufacturer>/<product>
directory. This file is normally called device.mk
:For Android O or Android P, using NN API version (1.0), the following should be added to device.mk
:
For Android P, a new version of the NN API is available (1.1), thus the following should be added to device.mk
instead:

For example, if the ArmNN driver has been built with the NN API 1.0, check for the following file:
Please Note: Android O is only compatible with NN API version 1.0.

tag.The GPU tuner is a feature of the Compute Library that finds optimum values for GPU acceleration tuning parameters. The recommended way of using it with ArmNN is to generate the tuning data during development of the Android image for a device, and use it in read-only mode during normal operation:
