Support for Microsoft Visual Studio 2008* Deprecated
In a future major release of Intel® IPP, support for use with Microsoft Visual Studio 2008 will be removed. Intel recommends that customers migrate to Microsoft Visual Studio 2012* at their earliest convenience.
Threading, within the deprecated multi-threaded add-on packages of the Intel® IPP library, is accomplished by use of the Intel® OpenMP* library. Intel® IPP 8.0 continues the process of deprecating threading inside Intel IPP functions that was started in version 7.1. Though not installed by default, the threaded libraries can be installed so code written with these libraries will still work as before. However, moving to external threading is recommended. For more information please see the deprecation feedback page.
Continuing the deprecation process started in Intel IPP 7.1, Intel IPP 8.0 deprecated more obsolete APIs:
- The majority of functions that use internal memory allocation are marked as deprecated, analogues without internal allocation are provided (for example, a pair of GetSize and Init instead of InitAlloc and Free). All threaded libraries should also be considered as deprecated.
Known Intel® IPP 8.0 Issues and Limitations:
- Intel® IPP static libraries are not compatible with Microsoft Windows Driver Development Kit* 2003.
- On Intel® 64 architecture (Windows* OS), dynamic and multi-threaded static libraries produce incorrect result for the ippiOpticalFlowPyrLK_16u_C1R function due to a threading issue. Single-threaded static library produces correct result.
- Flavors of Pyramid functions that operate on 16-bit data, overflow on some images and produce incorrect results.
- Some transcedental arithmetic functions produce not exact results for cases with the known answer like exp(0)==1 - the result differs by 1 ulp (0.9999999999).
- A call of ippiInitCpu() for Intel® 64 architecture with the CPU parameter that does not support Intel® 64 architecture, initializes incorrect library (PX is expected). To avoid this behavoir, check that the CPU parameter is not less than Intel® Streaming SIMD Extensions 3 (Intel® SSE 3).
- Re-initialization of the library in case of dynamic linking leads to unnecessary unload-reload of the same DLL. This may slightlly affect performance. Avoid re-initialization at the application side.
- Applying antialiasing option to the ippiResizeSqrPixel function with the Lanczos interpolation method leads to correct but shifted by 0.5 pixel (non-symmetrical) result.
- Documentation viewing issue with Microsoft Internet Explorer* 10 and Windows Server* 2012: If on Windows Server* 2012 you find that you cannot display help or documentation from within Internet Explorer 10, modifying a security setting for Microsoft Internet Explorer* usually corrects the problem. From Tools > Internet Options > Security, add “about:internet” to the list of trusted sites. Optionally, you can remove “about:internet” from the list of trusted sites after you are finished viewing the documentation.
The Intel® IPP 8.0 for Windows*, Linux* OS, and OS X* are available as:
- The installation package for both IA-32 and Intel® 64 architectures
- Online installer that downloads materials chosen during installation
and the following optional add-on packages:
- Intel® IPP for Windows* Cryptography Add-on
- Intel® IPP for Linux* OS Cryptography Add-on
- Intel® IPP for OS X* Cryptography Add-on
Cryptography for Intel® IPP is a Separate Download
Cryptography for Intel® IPP 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 or suite product containing IPP before installing the respective Cryptography for Intel® IPP package. Please note: the version of Intel IPP installed by the Intel® suites may not always match the latest (default) version of Cryptography for Intel IPP. To obtain Cryptography for Intel IPP, which is distributed separately from the main Intel IPP, please review this knowledge base article: Where do I download the Intel® IPP Cryptography libraries?
Intel® IPP SPIRAL Domain (ippGEN) is reinstated into the main 8.0 package
The SPIRAL subset (ippGEN) of the signal processing domain is distributed back into the main package. SPIRAL for Intel IPP contains the binaries and header files needed to utilize the functions contained in the ippGEN domain. 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.
