Description

X-LINUX-AI is an STM32 MPU OpenSTLinux Expansion Package that targets artificial intelligence for STM32MP1 Series microprocessors. It contains Linux® AI frameworks, as well as application examples to get started with some basic use cases such as computer vision (CV).

The examples provided in X-LINUX-AI use TensorFlow™ Lite models for image classification based on MobileNet v1, and for object detection based on the COCO SSD MobileNet v1 model. The face recognition application provided in X-LINUX-AI as a prebuilt binary is based on models retrained by STMicroelectronics. Contact the local STMicroelectronics support for more information about this application.

These examples use either the TensorFlow™ Lite inference engine supporting Python™ scripting and C/C++ applications, or the Google Edge TPU™ accelerator supporting Python™ scripting and C/C++application, or also the ONNX Runtime supporting Python scripting application. For the latter, the C/C++ ONNX Runtime API is also available but no application example is provided yet.

X-LINUX-AI runs on the STM32MP1 Series. It is demonstrated on the STM32MP157F-DK2 with a USB image sensor, and on the STM32MP157F-EV1 with its built-in camera module.
