 These are the step by step instructions on Cross-Compiling Arm NN under an x86_64 system to target an Arm64 Ubuntu Linux system. This build flow has been tested with Ubuntu 18.04 and 20.04 and it depends on the same version of Ubuntu or Debian being installed on both the build host and target machines. The instructions assume you are using a bash shell and show how to build the Arm NN core library, Protobuf, Tflite, Flatbuffer and Compute Libraries.

 # Arm NN Serialized Example model
 
-This is a really simple example of an Arm NN serialized model which is supported on Netron. It is based on SSD MobileNet V1 FP32 model available in the public model zoo (https://github.com/ARM-software/ML-zoo/tree/master/models/object_detection/ssd_mobilenet_v1/tflite_fp32), converted using the ArmnnConverter tool. The model is trained by Google and uses 300x300 input image. 
-More details on how to deploy this model using Arm NN SDK can be found here: https://developer.arm.com/documentation/102274/latest
