Overview

English | 简体中文

Note:

• Currently, most operators in the operator library run on the AI Core, and a few operators run on the AI CPU. By default, operators mentioned in this project refer to AI Core operators.
• For the introduction to AI Core and AI CPU, see the "Concepts, Principles, and Terms > Hardware Architecture and Data Processing Principles" section in Ascend C Operator Development.

This project provides development and invocation samples of AI Core operators and AI CPU operators. Developers can refer to the corresponding implementations based on actual conditions.
