Simd是开源的图像处理库，它提供了很多高性能的算法，这些优化算法主要由SIMD指令来实现，包括SSE、SSE2、SSSE3、SSE4.1、SSE4.2、AVX等，此库可以应用在windows/Linux 32bit/64bit等系统中。此库更新较频繁。此库的license是MIT。
下面详细介绍其在vs2010中的编译及使用：
1. 从http://sourceforge.net/projects/simd/?source=typ_redirect下载最新版本simd.2.2.27.443，解压缩；
2. 新建一个libSimd静态库工程，将/simd.2.2.27.443/simd/src/Simd目录下的.h、.cpp文件加入到此工程中，将../../../src/simd.2.2.27.443/simd/src/加入到C/C++--> General --> Additional Include Directories中，编译即可生成静态库，其实/simd.2.2.27.443/simd/prj/vs11中已经有了vs2012的工程配置，只是工程数太多，我把它们都放在一个工程里了；
3. 新建一个testSimd控制台工程，测试生成的libSimd库的正确性，相关代码如下：
