This chapter explains the structure of the Intel® Integrated Performance Primitives (Intel® IPP) software and some of the basic concepts used in the signal processing part of Intel IPP. It also defines function naming conventions in the manual, describes the supported data formats and operation modes.
The Intel IPP functions return the status of the performed operation to report errors and warnings to the calling program. The last value of the error status is not stored, and you need to decide whether to check it or not as the function returns. The status values are of the IppStatus type and are global constant integers.
Enables or disables flush-to-zero (FTZ) mode.
Initializes a vector to zero.
Creates a slope vector.
Adds product of two vectors to the accumulator vector.
Sums natural logarithms of each element of a vector.
