7.1 Release Notes

Performance and Optimization Changes:

Domain-Specific Changes:

  • The ippsResamplePolyphase functions were reinstated to the signal processing domain.
  • New image resize:
    • IppiResizeSpec holds precalculated coefficients based on input/output resolution combination. Multiple resizes which can be completed without recomputing them.
    • Separate functions for each interpolation method.
    • Significantly smaller executable size footprint with static linking.
    • Improved support for threading and tiled image processing.
    • For more information please see Resize Changes in Intel® IPP 7.1

Deprecations:

For more information please see Intel® IPP 7.1 Deprecated Features

  • The deprecation process for a selective list of features started, including full deprecation of the RR, DI, and GEN domains. Note: deprecation is not removal. Functions will remain usable while we gather feedback. Please let us know if removal of any of these functions will cause hardship. For more information please see Intel® IPP 7.1 Deprecated Features.
  • Internal function threading is deprecated. Threaded static libraries (_t) are available as a separate download. For more information please see Intel® IPP 7.1 Deprecated Features.
  • Several samples, including image and video processing codecs, were moved to legacy status.

Installation Changes:

  • Threaded static libraries (_t) are now available as a separate download. For more information please see Intel® IPP 7.1 Deprecated Features.
  • The Intel® IPP Reference Manual is no longer available with the product as uncompressed help. Help content for integration with Microsoft* Visual Studio* 2008 and 2010 continues to be provided with the Windows* OS product. The Intel® IPP Reference Manual (uncompressed help format) is available for download at http://software.intel.com/en-us/articles/intel-integrated-performance-primitives-documentation/
  • There were several API changes, including adding new resize variants and removing some deprecated since Intel® IPP 6.0, reinstating ippsResamplePolyphase, consolidation of ippsJoin_32f16s_D2L and ippsVLC* functions to audio coding, and removal of previously deprecated functions.
  • The samples build process has been improved. For more information please see Building the Intel® IPP 7.1 Samples.
  • The px/mx (generic) implementations, released for Intel® IPP 7.0, are not available for Intel® IPP 7.1. They were a one-time release with the 7.0 API, and are not compatible with 7.1.

Known Intel® IPP 7.1 Issues and Limitations:

  • ippiFilter_Round16s_8u_C3R: This function may produce an exception when executed on 4th Generation Intel® Core processors with a 32-bit Windows operating system. The ippiFilter_8u_C3R function may be a workaround.
  • ippiDistanceTransform_5x5_8u32f_C1R: This function may produce an exception when executed on 4th Generation Intel® Core processors with a 32-bit Windows operating system.
  • ippiResize functions: These functions work with even image resolutions only. Odd resolutions are cropped to an even size and return a warning.

Product Contents

The core Intel® IPP v7.1 for Windows* OS consists of two installation packages:

  • Intel® IPP for Microsoft* Windows* on IA-32 Architecture
  • Intel® IPP for Microsoft* Windows* on Intel® 64 Architecture

and the following optional add-on packages:

The core Intel® IPP v7.1 for Linux* OS consists of two installation packages:

  • Intel® IPP for Linux* on IA-32 Architecture
  • Intel® IPP for Linux* on Intel® 64 Architecture

and the following optional add-on packages:

There is no standalone installation of the Intel® IPP v7.1 for OS X*. The Intel® IPP 7.1 for OS X* is distributed as part of the Intel® Composer XE and Intel® C++ Composer XE product suites.

Intel® IPP Threaded Static Libraries are a Separate Download

Many Intel® IPP functions are threaded internally. This means that the internal implementation of the functions uses OpenMP* to automatically divide work among several threads when you use dynamic linking, or when you link with the multithreaded static versions of the libraries. To see the list of these functions, refer to the ThreadedFunctionsList.txt document available in the documentation directory of the Intel® IPP installation.

Threading at the application level is better for performance. Since the parallelism is managed at a higher level than the primitives this may also be referred to as "external" threading.

The Intel® IPP 7.1 installer contains the dynamic libraries (which are still threaded) and the single threaded static libraries. However, the multithreaded static libraries are now a separate download. After they are installed your multithreaded statically linked code will continue to work with internal threading.

Intel® IPP for Cryptography is a Separate Download

Intel® IPP for cryptography is a separate installation package that contains the binaries and header files needed to utilize the functions contained in the Intel® IPP cryptography domain. It is an add-on to the Intel® IPP library and, therefore, requires that the core Intel® IPP already be installed on your system. You must first install the standalone Intel® IPP, Intel® Cluster Studio XE, Intel® C++ Studio XE, Intel® Composer XE, Intel® Parallel Composer, Intel® Parallel Studio, or the Intel® Parallel Studio XE product before installing the respective Intel® IPP for cryptography package. Please note: the version of Intel® IPP installed by the Intel® Parallel suites may not always match the latest (default) version of Intel® IPP for cryptography.

To obtain Intel® IPP for cryptography, which is distributed separately from the main Intel® IPP, please review this knowledge base article: Intel® IPP for Linux* Cryptography Add-on.

Intel® IPP SPIRAL Domain (ippGEN) is a Separate Download

Please note: the process of deprecating the ippGEN domain begins in Intel® IPP 7.1. For more information please see http://software.intel.com/en-us/articles/intel-ipp-71-deprecated-features.

In order to decrease the size of the Intel® IPP installation package, the SPIRAL subset (ippGEN) of the signal processing domain is distributed as a separate library add-on. Go to the Intel® Software Development Products Registration to download the ippGEN component of the Intel® IPP.

SPIRAL for Intel® IPP is a separate installation package that contains the binaries and header files needed to utilize the functions contained in the ippGEN domain. It is an add-on to the Intel® IPP and, therefore, requires that the core Intel® IPP be already installed on your system. You must first install the standalone Intel® IPP, Intel® Cluster Studio XE, Intel® C++ Studio XE, Intel® Composer XE, Intel® Parallel Composer, Intel® Parallel Studio, or the Intel® Parallel Studio XE product before installing the respective SPIRAL add-on library.

The ippGEN package is an adjunct to the ippSP (Signal Processing) domain. It contains signal processing functions that have been optimized for non-ordinary size data sets, primarily in the class of FFT functions. If you have not used these "ippg" functions in the past, it is likely that you do not need to download and install this add-on library. However, there is no harm to installing this add-on with the core Intel® IPP.
