关于Intel IPP

Intel® IPP offers developers high-quality, production-ready, low-level building blocks for image processing, signal processing, and data processing (data compression/decompression and cryptography) applications.
…
Optimized for Performance

Intel IPP software building blocks are highly optimized using Intel® Streaming SIMD Extensions (Intel® SSE) and Intel® Advanced Vector Extensions (Intel® AVX, Intel® AVX2) instruction sets, so your application will perform faster than what an optimized compiler can produce alone. Just by plugging in these primitives, you will see 5X to 10X faster performance on your applications.

简单来说Intel Ipp库是Intel针对自家处理器进行高度优化的函数，能够提升诸多方面的性能，比如Opencv的图像处理性能。

下载及安装

IPP的官方下载地址：
https://software.intel.com/en-us/intel-ipp


邮箱里会收到一封邮件，比如我的这个：

点击download后，弹出一个网页，选择系统版本和要下载的软件，我选择的是windows：

点击Download Now就开始下载了，大小545MB
下载后，双击解压安装，如下地方记得输入之前说过的序列号。

配置

安装结束后，会弹出一个本地的配置说明文档（file:///C:/Program%20Files%20(x86)/IntelSWTools/documentation_2017/en/ipp/common/get_started.htm），主要由下面几个地方需要配置：
1. 系统环境变量
按照下图依次点击：

在Path中加入（根据个人路径不同，需要更改）：
;C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2017.0.109\windows\redist\intel64_win\ipp;C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2017.0.109\windows\redist\ia32_win\ipp
这里将32和64位的地方都加入了，（注意分隔符“；”），方便以后使用。
这里有一点需要注意的是，如果你的vs中的opencv项目选择的是32位，那么至少应该加入;C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2017.0.109\windows\redist\ia32_win\ipp

配置完成之后，需要重启电脑。。。
2. visual studio环境变量

注意方框里我使用的是32位编译器。
这里设置编译时的环境变量（对应32位，如果是64位，需要更改ia32_win为intel64_win），包括：
① 可执行文件目录。加入：
C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2017.0.109\windows\redist\ia32_win\ipp
② 包含目录。加入：
C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2017.0.109\windows\ipp\include
③ 库目录。加入：
C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2017.0.109\windows\ipp\lib\ia32_win
然后，设置连接器的环境变量：

加入（将下面的粘贴进去即可，不分32 64位）：
ippcc.lib
ippccmt.lib
ippch.lib
ippchmt.lib
ippcore.lib
ippcoremt.lib
ippcv.lib
ippcvmt.lib
ippdc.lib
ippi.lib
ippimt.lib
ipps.lib
ippsmt.lib
ippvm.lib
ippvmmt.lib
好了，加完这些，配置就OK了。

测试

file:///C:/Program%20Files%20(x86)/IntelSWTools/documentation_2017/en/ipp/common/get_started.htm
这里有一段代码，可以测试和打印出系统对IPP的支持情况。新建一个cpp文件，将如下复制进去，并编译，运行。如果编译并运行成功，那么说明IPP配置OK。
