2018

Initial Release

Release Notes

What's New in Intel® IPP 2018:

• Added new functions to support the LZ4 data compression and decompression. This release also introduces the patch files for LZ4 source to provide drop-in optimization with the Intel® IPP functions.
• Introduced the standalone cryptography packages. The cryptography functions no longer depend on the main Intel® IPP packages, and can be used without the main Intel® IPP packages.
• Introduced the optimization code for the GraphicsMagick source. The code can provide drop-in optimization on GraphicsMagick with the Intel® IPP functions:
  • The code supports GraphicsMagick version 1.3.25, and provides optimization for the following GraphicsMagick APIs: ResizeImage, ScaleImage, GaussianBlurImage, FlipImage, and FlopImage.
  • The optimization code can improve the APIs performance by up to 4x, depending on the functionality, input parameters, and processors.
• Made the Integration Wrappers APIs part of the Intel® IPP packages.
• Computer Vision:
  • Added the 64-bit data length support for Canny edge detection functions (ippiCanny_32f8u_C1R_L).
• Color Conversion:
  • Added the ippiDemosaicVNG functions that support the demosaicing algorithm with VNG interpolation.
• Cryptography:
  • Added the Elliptic Curves key generation and Elliptic Curves based Diffie-Hellman shared secret functionality.
  • Added the Elliptic Curves sign generation and verification functionalities for the DSA, NR, and SM2 algorithms..
• Performance:
  • Extended optimization for the Intel® Advanced Vector Extensions 512 (Intel® AVX-512) and Intel® Advanced Vector Extensions 2 (Intel® AVX2) instruction sets.
  • Improved performance of LZO data compression functions on Intel® AVX2) and Intel® Streaming SIMD Extensions 4.2 (Intel® SSE4.2).
• Other Changes:
  • Removed support for Intel® Pentium® III processor. The minimal supported instruction set is Intel® Streaming SIMD Extensions 2 (Intel® SSE2).
  • Removed support for the Intel® Xeon Phi™ x100 product family coprocessor (formerly code name Knights Corner) in this release.

    The Intel® Xeon Phi™ x100 product family coprocessor (formerly code named Knights Corner) was officially announced end of life in January 2017. As part of the end of life process, the support for this family will only be available in the Intel® Parallel Studio XE 2017 version. Intel® Parallel Studio XE 2017 will be supported for a period of 3 years ending in January 2020 for the Intel® Xeon Phi™ x100 product family. Support will be provided for those customers with active support.

Known Issues:

• The release only provides optimization on Intel® SSE4.2 and later instructions for the morphology image processing functions. Users may notice performance degradation in those functions on some old processors. If the old instructions optimization for the morphology functions is important for your applications, please submit your feedback through the product support.

Threading Notes:

• To support the internal threading in the Intel® IPP functions, Intel® IPP provides the Threading Layer APIs in the platform-aware functions. These APIs can support both 64-bit object sizes (for large size images and signal data) and internal threading in Intel® IPP functions. Check the “Threading Layer Functions” pat in the Intel® IPP Developer Reference to get more information on these APIs., Your feedback on extending the new threading functions is welcome.
• The legacy Intel IPP threaded libraries are available by the custom installation, and the code written with these libraries will still work as before. However, the threaded library will not expand its threading functions, and the new threading will be developed only in the new Intel® IPP threading layer APIs. User’s application is recommended to use the new Intel® IPP threading layer APIs or implement the external threading in their applications.
