Is there an IPP function to detect the processor type?

In Intel IPP v6.0, there is a new function named ippGetCpuFeatures() (*) that can be used to detect your processor features. It is declared in ippcore.h. This function retrieves CPU features like those returned by the Linux function CPUID.1 and stores them consecutively in the mask pFeaturesMask. The following table lists features stored in the mask. Mask values are defined in the ippdefs.h file.

Note as of version 6.1 the IPP library supports the new Intel® Advanced Vector Extensions ( Intel® AVX) instruction.



 Please refer to Intel IPP developer reference guide for latest processor.

Note that the legacy IPP function ippGetCpuType() (**) mixed CPU types and SIMD instruction types. Starting with version 6.0 of the library we strongly recommend using this new function ippGetCpuFeatures() to detect the CPU feature.

Additionally, please download the Intel IPP samples (***) which contain an application that can be used to detect a range of CPU info. This free sample, with source code, is located in the ipp-samples\advanced-usage\cpuinfo directory of the IPP samples.

Processor Architecture Table

The following table was copied from an Intel Compiler Pro options article describing some compiler architecture options. It contains a fairly complete list of which Intel processors support which SIMD instructions. For the latest table please refer to the original article; it gets updated on a regular basis. Please note that the behavior of the Intel Compiler SIMD dispatcher described in that article does not apply to the Intel IPP library. The Intel IPP library dispatching mechanism behaves differently than that found in the Intel Compiler products, and may behave differently than other Intel library products.

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.
