目标：IPP软件从X86平台移植到ARM平台

移植函数：

指数函数：ippsExp_32f_A24
三角函数：ippsCos_32f_A24，ippsSin_32f_A24
正弦波生成函数：ippsTone_16s，ippsTone_32f
三角波生成函数：ippsTriangle_32fc

1.安装环境

官网下载ipp环境安装包：https://www.intel.cn/content/www/cn/zh/developer/tools/oneapi/ipp.html

安装环境

修改环境变量：

临时修改：

source /opt/intel/oneapi/setvars.sh

永久修改：

echo "source /opt/intel/oneapi/setvars.sh" >> ~/.bashrc
