Prerequisites (Windows* OS)

Set Environment Variables

After installing Intel IPP, set the PATH, LIB, and INCLUDE environment variables by running the script appropriate to your target platform architecture. The scripts are available in <install dir>\env.

By default, the <install dir> is C:\Program files (x86)\Intel\oneapi. See Intel IPP high-level directories structure.

Configure Your IDE Environment to Link with Intel IPP

Option 1. After a default installation of the Intel® IPP, you can easily configure your project to automatically link with Intel IPP. Configure your Microsoft* Visual Studio* project for automatic linking with Intel IPP as follows:

1. Go to Project> <your_project_name> Properties> Configuration Properties> Intel Libraries for oneAPI.

2. Change the Use Intel® IPP property setting by selecting one of the options to set the include directories and the linking model. See linking options for more details.

Option 2. To manually configure your Microsoft* Visual Studio* development system for linking with the Intel IPP library, follow the steps below. Though some versions of the Visual Studio* IDE may vary slightly in the menu items mentioned below, the fundamental configuring steps are applicable to all these versions.

1. In Solution Explorer, right-click your project and click Properties.

2. Select Configuration Properties > VC++ Directories and set the following from the Select directories for drop down menu:

   • Include Files menu item, and then type in the directory for the Intel IPP include files (default is <install_dir>\include)

   • Library Files menu item, and then type in the directory for the Intel IPP library files (default is <install_dir>\lib\<arch>)

   • Executable Files menu item, and then type in the directory for the Intel IPP executable files (default is <install_dir>\redist\<arch>)

Build and Run Your First Intel® IPP Application (Windows* OS)

The code example below represents a short application to help you get started with Intel IPP:

#include <stdio.h>
#include "ipp.h"

#define PRINT_INFO(feature, text) printf("  %-30s= ", #feature); \
      printf("%c\t%c\t", (cpuFeatures & feature) ? 'Y' : 'N', (enabledFeatures & feature) ? 'Y' : 'N'); \
      printf( #text "\n")

int main(int argc, char* argv[])
{
      const       IppLibraryVersion *libVersion;
      IppStatus   status;
      Ipp64u      cpuFeatures, enabledFeatures;

      ippInit();                      /* Initialize Intel® IPP library */
      libVersion = ippGetLibVersion();/* Get Intel® IPP library version info */
      printf("%s %s\n", libVersion->Name, libVersion->Version);

      status = ippGetCpuFeatures(&cpuFeatures, 0);/* Get CPU features and features enabled with selected library level */
      if (ippStsNoErr != status) return status;
      enabledFeatures = ippGetEnabledCpuFeatures();
      printf("Features supported: by CPU\tby Intel® IPP\n");
      printf("------------------------------------------------\n");

}

This application consists of three sections:

1. Initialize the Intel IPP library. This stage is required to take advantage of full Intel IPP optimization. With ippInit(), the best implementation layer is dispatched at runtime; otherwise, the least optimized implementation is chosen. If the Intel IPP application runs without ippInit(), the Intel IPP library is auto-initialized with the first call of the Intel IPP function from any domain that is different from ippCore. In certain debugging scenarios, it is helpful to force a specific implementation layer using ippSetCpuFeatures(), instead of the best as chosen by the dispatcher.

2. Get the library layer name and version. You can also get the version information using the ippversion.h file located in the <install_dir>\include directory.

3. Show the hardware optimizations used by the selected library layer and supported by CPU.
