Computes the size of the constant structure and work buffer for single-rate FIR filtering.
IppStatus ippsFIRSRGetSize(int tapsLen, IppDataType tapsType, int* pSpecSize, int* pBufSize);
ipps.h
Headers: ippcore.h, ippvm.h
Libraries: ippcore.lib, ippvm.lib
tapsLen |
Length of the FIR filter. |
tapsType |
Data type of the coefficients. The supported values are ipp32f, ipp32fc, ipp64f, and ipp64fc. |
pSpecSize |
Pointer to the size of the internal constant specification structure. |
pBufSize |
Pointer to the size of the work buffer required for FIR filtering. |
This function computes the following:
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error when one of the specified pointers is NULL. |
ippStsSizeErr |
Indicates an error when the tapsLen value is less than, or equal to zero. |
ippStsDataTypeErr |
Indicates an error when the specified taps type is not supported. |
