### AI overview

This tutorial examines PIE processor instruction extensions on ESP32-S3 and ESP32-P4. It covers their instruction architecture, formats, applications, and differences in hardware-loop support and accumulator size.

### Source excerpt

The recent breakthroughs in artificial intelligence technology in such fields as image recognition, speech recognition, and natural language processing have opened up more possibilities for embedded system applications. When attempting to deploy AI model inference on embedded devices such as the ESP32-P4, we always strive to minimize inference time as much as possible to meet real-time requirements.
