Intel® Atom™ Processors support in the Intel® Integrated Performance Primitives (Intel® IPP) Library
All versions of the Intel® IPP library will run on Intel® Atom™ processors. The table below represents the Intel IPP library functions that have been "hand-tuned" for optimal performance on Intel Atom processors in version 7.0.2 of the library.
Hand-tuned optimizations designed to maximize performance of the Intel IPP library on Intel Atom processors were added beginning with v6.0 of the Intel IPP library. For maximum performance on Intel Atom processors, we recommend that you upgrade to version 7.0 of the Intel IPP library.
Both static and dynamic/shared libraries in v7.0 of the Intel IPP library include Intel Atom processor optimizations. Applications linked with versions 7.0 of the Intel IPP library will be dispatched to the "s8" optimized library for IA-32 and the "n8" library for Intel® 64 whenever your application executes on an Intel Atom processor.
In the v6.x Intel IPP library, only the dynamic/shared libraries contain Intel Atom processor optimizations; there are no Intel Atom processor optimizations in the v6.x dispatched static libraries. However, the v6.x dispatched static libraries will safely run on an Intel Atom processor by dispatching to the v8/u8 libraries optimized for the Merom microarchitecture (Intel Core 2 processor), which is also designed for use with the same Intel Supplemental SSE3 SIMD instruction set (SSSE3) that Intel Atom processors support. A separate non-dispatched static Intel IPP library for Linux* is available on the IA-32 platform (and as part of the Intel Atom SDK).
The following list of functions have been hand-optimized for the Intel Atom processor for the version of the Intel IPP library listed at the beginning of this article.
Note: every Intel IPP library primitive is available for use with the Intel Atom processor, this list simply shows those functions which have been specially hand-tuned for the Intel Atom processor; hand-tuning is not required to achieve optimum performance for all IPP functions. If you have some specific Intel IPP functions that are not listed in the following table, and would like to see them added to the priority list for Atom optimization, please create a thread on the IPP forum stating which functions you would like to see added to the Atom optimization priority list.
Functions not listed above are either hand-optimized for the Merom microarchitecture (SSSE3) or for prior SIMD instruction sets that are compatible with the Intel Atom processor (such as SSE2). In addition, the entire Intel Atom optimized library is compiler-optimized for the Intel Atom processor using the Intel Compiler xSSE3_ATOM switch (enable Atom optimizations) in order to take advantage of features unique to the Intel Atom processor.
