IVGCVSW-3064 Implementing our own version of the compliantWithV1_0(operation) and convertToV1_0(operation) functions Change-Id: I2c0927013e16baefcc7290bbcfc8e76c4a645c35 Signed-off-by: Éanna Ó Catháin <eanna.ocathain@arm.com>
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 Android P the vendor manifest.xml requires the Neural Network HAL information.

For example, if the ArmNN driver has been built with the NN API 1.0, check for the following file:

tag.The GPU tuner is a feature of the Compute Library that finds optimum values for GPU acceleration tuning parameters. There are three levels of tuning: exhaustive, normal and rapid. Exhaustive means that all lws values are tested. Normal means that a reduced number of lws values are tested, but that generally is sufficient to have a performance close enough to the exhaustive approach. Rapid means that only 3 lws values should be tested for each kernel. 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:
