Intel® Integrated Performance Primitives (Intel® IPP) library provides threading layer (TL) functions for image processing. It is a set of functions that are implemented as wrappers over Intel IPP platform-aware functions by using tiling and multithreading with OpenMP*. For implementation details, please see the corresponding source code files.

The API of TL functions is similar to the API of other Intel IPP functions and has only slight differences. You can distinguish Intel IPP TL functions by the _LT or _T suffix in the function name, for example, ippiAdd_8u_C1RSfs_LT. See Extensions for more information about function naming.

For more information about the TL functions usage, refer to the Intel IPP Developer Guide.

Optimization Notice

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
