Why are the functions fast?
 Intel® IPP functions exploit the instruction set architecture by
– processing multiple data elements in parallel
– Streaming SIMD Extensions like SSE4
– processing data in larger chunks with each instruction
 Intel® IPP functions exploit the processor micro architecture by
– pre-fetching data and avoiding cache blocking
– resolving data and trace cache misses
– avoiding branch mispredictions

Function implementation
Intel IPP uses codes optimized for various central processing units (CPUs). Dispatching refers to detection of
your CPU and selecting the corresponding Intel IPP binary. For example, ippiv8-7.0.dll in the \redist\ia32\ipp
directory, reflects the imaging processing libraries optimized for the Intel(R) Core(TM) 2 Duo processors.

Threading control flexibility in Intel® IPP
Intel® IPP are thread-safe. It supports threading above it:
 Intel® IPP threading functions are self-contained, which do not necessarily require application
level threading to use OpenMP*

Intel® IPP threading can be disabled or fine-tuned by applications
In a case that application needs fine-grained threading control
 Call the function ippSetNumThreads with argument 1
 Use static library to avoid OpenMP dependency
 Use completely single thread ideal for kernel development

Dynamic linking
Dynamic linking is the simplest method and the most commonly used. It takes full advantage of
the dynamic dispatching mechanism in the dynamic link libraries (DLLs)
To dynamically link with Intel ® IPP, follow these steps:
1. Include ipp.h in your application. This header includes the header files for all Intel IPP
functional domains.
2. Use the normal Intel IPP function names when calling the functions.
3. Link corresponding domain import libraries. For example, if you use the function
ippsCopy_8u, link to ipps.lib.
4. Make sure that the run-time libraries are on the executable search path at run time.
Run the ippvars.bat from directory \ipp\bin to ensure that the application loads the
appropriate processor-specific library.
20
Optimization Notice

Static Linking with Dispatching
To use the static linking libraries, you need to link to all required domain libraries
ipp*_l.lib, adding ippcore_l.lib and libraries on which domain libraries depend (see next
section below). The * denotes the appropriate function domain.
If you want to use the Intel IPP functions threaded with the OpenMP*, you need to
link to the threaded versions of the libraries ipp*_t.lib, ippcore_t.lib, and libiomp5md.lib.
All domain-specific and core libraries are located in the \ipp\lib\<arch> directory.

Developer resources are needed to create and
 Smallest installation package to

requires rebuilding the custom DLL
Not appropriate for kernel-mode/device-driver/ring-0

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
