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.

IPP performance improvement on switching to VS 2013 from VS 2010?

I am getting a performance improvement on switching to VS2013. 7x7 convolution on 14kx7k image which was taking 2300ms is now taking 690ms in VS2013. Though it is good, I want to understand the reason for this. On searching the web I found out…

starting index and ending index of elements in a array(vector) that are greater than a value

Given a array like this: {1, 3, 11, 2, 24, 13, 5....} The array length might be larger than 1,000. If the value of the element is inappropriate, such as larger than 10, it shall be replaced by appropriate value. In this case, the appropriate value…

Building MFCC filter banks in the same way as Intel's performance primitives

I'm trying to build the triangular filters for generating MFCCs. I have existing code based on IPP 6 but as IPP 8 is on its way now I'd really like to get an implementation that works and isn't reliant on an old, now unsupported, library. I've…

Intel IPP library requirements

So I am trying to compile an Intel IPP sample application that comes with the library -- string matching --, and I don't seem be able to leverage the IPP instructions. The computational time stays the same when I disable one of the cores on my…

Frequency Shift without Intermediate Buffer using IPP

I have a buffer full of real/imaginary sample values of a signal, and would like to shift the signal in the frequency domain by multiplying a sinusoid. I see myself with four options: some IPP function (I could not find one though) manually…

Does IPP work on Windows Azure?

Supposing one were to compile a native dll using IPP (Intel Performance Primitives), and deploy it to Azure using a managed wrapper, would the performance gains from IPP be realized?
