Sets the delay line contents in the FIR LMS filter.

Syntax

IppStatus ippsFIRLMSGetDlyLine_32f(const IppsFIRLMSState_32f* pState, Ipp32f* pDlyLine, int* pDlyLineIndex);

IppStatus ippsFIRLMSGetDlyLine32f_16s(const IppsFIRLMSState32f_16s* pState, Ipp16s* pDlyLine, int* pDlyLineIndex);

IppStatus ippsFIRLMSSetDlyLine_32f(IppsFIRLMSState_32f* pState, const Ipp32f* pDlyLine, int dlyLineIndex);

IppStatus ippsFIRLMSSetDlyLine32f_16s(IppsFIRLMSState32f_16s* pState, const Ipp16s* pDlyLine, int dlyLineIndex);

Parameters

pState	Pointer to the FIR LMS filter state structure.
pDlyLine	Pointer to the tapsLen-length array holding the delay line values.
dlyLineIndex	Initial index of the delay line to be stored in the filter state structure pState.

Description

The function ippsFIRLMSSetDlyLine is declared in the ipps.h file. This function copies the delay line values from pDlyLine, and the current delay line index from dlyLineIndex, and stores them into the state structure pState.

Before calling the function ippsFIRLMSSetDlyLine the filter state structure must be initialized by the function ippsFIRLMSMRInitAlloc.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when one of the specified pointers is NULL.
ippStsContextMatchErr	Indicates an error when the state identifier is incorrect.
