1# Arm NN Support Library Neural Networks driver
2
3This directory contains the Arm NN Support Library for the Android Neural Networks API.

5# Passing parameters to the support library runtime.
6
7The support library inherits it's parameters from the Arm NN Android Neural Networks driver. Parameters are passed to it through an environment variable, ARMNN_SL_OPTIONS. A full list of parameters are available ./canonical/DriverOptions.cpp.

11## Running NeuralNetworksSupportLibraryTest
12
13This test suite takes as it's first argument the path to a shared object implementation of the support library. Any library dependencies should be resolvable through the LD_LIBRARY_PATH mechanism. Setting ARMNN_SL_OPTIONS will pass parameters to the Arm NN Support Library Neural Networks driver.
14
15Here we assume that Bash is the current shell and specify "-v" to enable verbose logging and "-c CpuAcc" to direct that the Neon(TM) accelerator be used.

20## Running TfLite Benchmarking tool
21
22This tools' parameters are described [here](https://www.tensorflow.org/lite/performance/measurement). The support library specific parts are to specify the path to the library and to ensure that ARMNN_SL_OPTIONS is set in the environment.
