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.

How can I verify that openCV has found, and is using IPP?

I've set the cmake defines so that I should be building with IPP support enabled, but I'd like to verify that this is the case. Since the IPP libs are statically linked I can't just check the resulting library files.

High performance comparison of signed int arrays (using Intel IPP library)

We're trying to compare two equally sized native arrays of signed int values using inequality operations, <, <=, > and >=, in a high performance way. As many values are compared, the true/false results would be sotred in a char array of the same…

Is it required to check 16 byte memory alignment when create a Mat of opencv?

I remember when using intel ipp, the width of image has to be aligned with 16 byte boundary. which means if width % 16 != 0, need fill a few bytes at the end of each row. Does opencv has this kind of requirement?

Using the Intel Performance Primitives FFT function, ippsConjPack_64fc, why is the output size the same as the input size?

I'm doing a forward FFT using ippsFFTFwd_RToPack_64f(pSrc.data(), pDst.data(), pSpec64, pBuffer), which writes waveformLen elements to pDst (pSrc.size() == waveformLen). Then, I'm trying to convert pDst to complex numbers, with…
