# Integrated Performance Primitives

Intel Integrated Performance Primitives (Intel IPP) is an extensive library of ready-to-use, domain-specific functions that are highly optimized for diverse Intel architectures. Its royalty-free APIs help developers take advantage of single instruction, multiple data (SIMD) instructions.
The library supports Intel and compatible processors and is available for Linux, macOS and Windows. It is available separately or as a part of Intel oneAPI Base Toolkit.
Intel IPP releases use a semantic versioning schema, so that even though the major version looks like a year (YYYY), it is not technically meant to be a year. So it might not change every calendar year.

## Features

The library takes advantage of processor features including MMX, SSE, SSE2, SSE3, SSSE3, SSE4, AVX, AVX2, AVX-512, AES-NI and multi-core processors.
Intel IPP includes functions for:
* Video decode/encode
* Audio decode/encode
* JPEG/JPEG2000/JPEG XR
* Computer vision
* Cryptography
* Data compression
* Image color conversion
* Image processing
* Ray tracing and rendering
* Signal processing
* Speech coding
* Speech recognition
* String processing
* Vector and matrix mathematics

## Organization

Intel IPP is divided into four major processing groups: signal processing (with linear array or vector data), image processing (with 2D arrays for typical color spaces), data compression, and cryptography.
Half the entry points are of the matrix type, a third are of the signal type, and the remainder are of the image and cryptography types. Intel IPP functions are divided into 4 data types: data types include 8u (8-bit unsigned), 8s (8-bit signed), 16s, 32f (32-bit floating-point), 64f, etc. Typically, an application developer works with only one dominant data type for most processing functions, converting between input to processing to output formats at the end points.
