Introduction to the KVSIP

Overview

This document describes the structure, operations, and main functions of the Kunpeng VSIP (KVSIP for short). Functions in this document include basic vector computing, basic matrix computing, and fast Fourier transform. These functions adapt to Kunpeng servers and enable ultimate performance optimization based on Kunpeng processors. To ensure the optimal performance, the interfaces do not verify all input parameters. The validity and reasonableness of the input parameters are ensured by the services that call the interfaces.
