IPP是一个广泛的现成可用、特定于域的函数库，针对不同的英特尔®；体系结构进行了高度优化。其免版税API可帮助开发者：

利用单指令多数据（SIMD）指令

提高计算密集型应用程序的性能，包括信号处理、数据压缩、视频处理和加密

减少软件开发和维护的成本和上市时间

核心是优化实现：

These software building blocks are highly optimized using Intel® Streaming SIMD Extensions 2, Intel® Advanced Vector Extensions 2 (Intel® AVX2), and Intel® Advanced Vector Extensions 512 (Intel® AVX-512) instruction sets.

访问数千个优化功能，涵盖常用的基本算法，包括用于创建以下内容的算法：

数字媒体

企业数据

嵌入式通信

科学、技术和安全应用

该库包括2500多个用于图像处理的原语，1300个用于信号处理，500个用于计算机视觉，300个用于密码。

优化当前和未来英特尔®；平台的CPU性能。每次指令集升级时，都会添加一个新的实现层。以前的实现与以前一样工作，但可以从新硬件功能中受益的功能在新体系结构发布之前会进行更新和验证。

解锁新硬件带来的性能提升。立即开始使用新的CPU功能，而不是为了其他优化而中断开发周期。在大多数情况下，性能提升是自动的。对于其他情况，您只需要重新编译。
