Introduction

You can use the Development Assistant to create Kunpeng application projects. It supports C and C++. During coding, it automatically queries the function library provided by the Kunpeng Library, as well as highlights and associates those replacement libraries and functions. It has the following features:

Kunpeng application projects: You only need to perform simple input and selection on the Create Kunpeng Application Project page to build empty projects and general-purpose computing, secure computing, high-performance computing (HPC), Data Processing & Acceleration Kit (DPAK), and data I/O application projects.
Dictionary management: Supports online (automatic) and offline update of the function dictionary in the library.
Coding assistance: Provides hints and function search for functions in the Kunpeng Library; associates and highlights the tuned functions in the Kunpeng Library during coding.

The Development Assistant supports the following libraries and high-performance open source components.

	SPDK	The Storage Performance Development Kit (SPDK) aims to improve efficiency and performance by using network, processing, and storage technologies. By running software designed for hardware, SPDK has proven capable of millions of I/O reads per second by using multiple processor cores and NVMe drivers for storage, without the need for offload hardware.
