 Inference Engine uses a plugin architecture. Inference Engine plugin is a software component that contains complete implementation for inference on a certain Intel® hardware device: CPU, GPU, VPU, etc. Each plugin implements the unified API and provides additional hardware-specific APIs.

 Common Workflow for Using the Inference Engine API
----------------------------
+--------------------------------------------------
 The common workflow contains the following steps:
 
 1. **Create Inference Engine Core object** - Create an `InferenceEngine::Core` object to work with different devices, all device plugins are managed internally by the `Core` object. Register extensions with custom nGraph operations (`InferenceEngine::Core::AddExtension`).
