Where to Find the Release 

Intel® Integrated Performance Primitives (Intel® IPP)  

Intel® IPP 2022.1.0

System Requirements

What's New 

• Added new inplace API for MulC functionality for images
• Optimized half-precision floating point(fp16) Discrete Fourier Transform (DFT) and Inverse Discrete Fourier Transform (IDFT) for the length of 1728, 1800, 2304, 2592, 2880 and 3072
• Improved the performance on Intel® Advanced Vector Extensions 512 (Intel® AVX512) processor systems for the APIs: ippiHog, ippiSet, ippsMagnitude_16sc32f, ippsAutoCorrNorm_64f, ippiConvert_32f8u/16s8u/16u8u

Bug fixes

• ippiFilterBilateral_8u (all mods) is fixed and works for L2 norm (ippDistNormL2) parameter instead of zero output.
• Fixed a correct suffix in "IPPConfig.cmake" file for Linux system
• Fixed a regression in norm functionality in OpenCV
• Added the description for ippsFIRMR32f_32fc function in documet FIRMR

Deprecation Notices

• Optimizations for architecture n8 (Intel® SSSE3) and e9 (Intel® AVX)  code path are deprecated, Intel® SSE is instead.

Also new general optimizations for functions ippiYCbCr422_8u_P3C2R, ippiYCCToRGB_8u_AC4R, ippiRGBToYCC_8u_AC4R, ippiRGBToYCC_8u_C3R, ippiYCCToRGB_8u_C3R, ippiXYZToRGB_8u_AC4R, ippiXYZToRGB_8u_C3R, ippiRGBToXYZ_16s_C3R, ippiRGBToXYZ_16s_AC4R, ippiXYZToRGB_16u_AC4R, ippiXYZToRGB_16u_C3R, ippiXYZToRGB_16s_AC4R, ippiXYZToRGB_16s_C3R, ippiYCCToRGB_16s_AC4R, ippiYCCToRGB_16s_C3R, ippiRGBToYCC_16u_C3R. 
• Extended optimizations in signal processing targeting Intel® Xeon® Processors with efficiency cores (E-cores) for functions ippsNorm_L2_16s32f, ippsNorm_L2_16s32s_Sfs, ippsNorm_L2Sqr_16s64s_Sfs. 
• Fixed error in Intel® IPP Signal Processing Windowing function ippsWinKaiser_32f_I. 
• Extended support GraphicsMagick version 1.3.38.
• Enabled Intel® Control-flow Enforcement Technology (Intel® CET) 

Known Issues and Limitations 

• CMake config files doesn't work properly with shared libraries (when CMake variable IPP_SHARED is set to ON) on Linux in IPP 2022.0.0 release. As a temporary workaround, please, replace IPP_MAJOR_VERSION with IPP_INTERFACE_VERSION_MAJOR on the line 205 of the file $IPPROOT/lib/cmake/ipp/IPPConfig.cmake.

• This release of Intel® Integrated Performance Primitives has been built with the new secure and powerful Intel® oneAPI DPC++/C++ Compiler.  As a result, we’ve noted some performance regressions in our testing, which will be addressed in the subsequent releases.  If these regressions are thought to be impacting your application in a negative way or you have specific questions, please contact  Intel® oneAPI Products Support. 

Unsupported or Discontinued Features 

• Intel® IPP 32-bit binaries are dropped in this release  

• Intel® IPP char domain is dropped in this release.
