FDPFwd

Performs frequency domain prediction procedure and calculates prediction error.

Syntax

IppStatus ippsFDPFwd_32f(const Ipp32f* pSrc, Ipp32f* pDst, IppsFDPState_32f* pFDPState);

Parameters

pSrc	Pointer to the input data array.
pDst	Pointer to the data array to be filled with prediction errors.
pFDPState	Pointer to the predictor specific state structure.

Description

This function is declared in the ippac.h header file. The function ippsFDPFwd applies frequency domain prediction procedure to the input signal pSrc and stores prediction errors in the pDst vector.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when the pFDPState pointer is NULL.
ippStsContextMatchErr	Indicates an error when the state structure is invalid.
ippStsMisalignedBuf	Indicates misaligned arrays. Supply aligned data for better performance.
