Questions related to Intel Integrated Performance Primitives (IPP), a multi-threaded library of functions for multimedia and data-processing applications.

Intel Integrated Performance Primitives (Intel IPP) is an extensive library of "algorithmic building blocks" for multimedia, data-processing, and communications applications. It supports multiple threads and has been highly optimized for Intel-family microprocessors, making extensive use of SIMD instructions (e.g., MMX, SSE, and AVX). The Windows, Linux, Android, and macOS environments are supported.

The library supports a wide range of functions for various domains and also provides for an OpenMP configuration, which can allow certain functions to run on multiple cores.

Why do some functions of Intel IPP do not support unsigned bytes?

I noticed that some (maybe most, I didn't check all of them) functions of the Intel® Integrated Performance Primitives (IPP) do not support signed bytes (8s), such as SortAscend and SortDescend and Copy, for example. I cannot think of a reason why…
