Common Functions

This section describes the Intel IPP functions that perform special operations common for all domains. For example, the function ippGetStatusString gets a brief description of the status code returned by the Intel IPP software. The function ippGetCpuType retrieves the type of the processor in the system running the software. The function ippGetCpuClocks gets the current number of processor clocks, which is widely used for operations timing. The functions ippSetFlushToZero and ippSetDenormAreZeros enable or disable special processor modes. The function ippAlignPtr performs pointer alignment. The functions ippMalloc and ippFree allow to allocate and free the memory block aligned to 32-byte boundary. The specific subset contains functions to control the dispatching of the merged static libraries. All these functions are grouped in the separate sub-library called ippcore.

ippGetStatusString
Translates a status code into a message.
ippGetCpuType
Returns a processor type.
ippGetCpuClocks
Returns a current value of the time stamp counter (TSC) register.
ippGetCpuFreqMhz
Estimates the processor operating frequency.
ippGetCpuFeatures
Retrieves the processor features.
ippGetEnabledCpuFeatures
Returns a features mask for enabled processor features.
ippGetNumCoresOnDie
Returns the number of cores for the multi-core processors.
ippGetMaxCacheSizeB
Returns maximum size of the L2 and L3 caches of the processor.
ippSetFlushToZero
Enables or disables flush-to-zero mode.
ippSetDenormAreZeros
Enables or disables denormals-are-zero mode.
ippAlignPtr
Aligns a pointer to the specified number of bytes.
ippSetNumThreads
Sets the number of threads in the multithreading environment.
ippGetNumThreads
Returns the number of existing threads in the multithreading environment.
ippSetAffinity
Binds OpenMP threads to OS processors.
ippMalloc
Allocates memory aligned to 32-byte boundary.
ippFree
Frees memory allocated by the function ippMalloc.
