= Neural Processing Unit

The Gateworks Venice SBCs that are using the i.MX8M Plus processors have a built in Neural Processing Unit (NPU) for machine learning. 
 * All GW74xx use the i.MX8M Plus processor
 * Any GW71xx, GW72xx and GW73xx using a GW702x SOM module will use the i.MX8M Plus processor

The NPU operatines up to 2.25 TOPS. 

NXP uses the term eIQ, which is 'edge intelligence'. NXP has a eIQ ML software environment for neural networks (NN).

With eIQ, there are 4 inference engines – OpenCV, Arm® NN, Arm CMSIS-NN and !TensorFlow Lite


Some of the default NXP Yocto software has examples in the directory /usr/bin/tensorflow-lite-2.4.0/examples
