OpenVINO™ Paddle Frontend Architecture

The diagram below shows the Paddle Frontend architecture and its interaction with OpenVINO Frontend API and Core APIs.

• The input to the Paddle Frontend is a PaddlePaddle protobuf model, and the output is the ov::Model which is semantically equivalent to the input.
• Paddle Frontend is an implementation of the OpenVINO Frontend, which implements two main interfaces. The first interface is load, which reads a Paddle protobuf model and represents it using InputModel with OpPlaces and TensorPlaces. The second interface is convert, which represents the InputModel with ov::Model by semantically mapping these Places to the OpenVINO opset.
