FIRSRGetSize

Computes the size of the constant structure and work buffer for single-rate FIR filtering.

Syntax

IppStatus ippsFIRSRGetSize(int tapsLen, IppDataType tapsType, int* pSpecSize, int* pBufSize);

Include Files

ipps.h

Domain Dependencies

Headers: ippcore.h, ippvm.h

Libraries: ippcore.lib, ippvm.lib

Parameters

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.

Description

This function computes the following:

Return Values

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.
