FIRSparseSetDlyLine

Sets the delay line contents in the sparse FIR filter state structure.

Syntax

IppStatus ippsFIRSparseSetDlyLine_32f(IppsFIRSparseState_32f*
pState
, const Ipp32f*
pDlyLine
);
IppStatus ippsFIRSparseSetDlyLine_32fc(IppsFIRSparseState_32fc*
pState
, const Ipp32fc*
pDlyLine
);

Parameters
pState
Pointer to the FIR filter state structure.
pDlyLine
Pointer to the array holding the delay line values.
Description
This function copies the delay line values from
pDlyLine
and stores them into the state structure
pState
. The source array
pDlyLine
must contain samples in the reverse order as compared to the order of samples in the source vector.
Before calling
ippsFIRSparseSetDlyLine
, the corresponding filter state structure must be initialized with the
FIRSparseInit
function.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error when the
pState
pointer is
NULL
.
ippStsContextMatchErr
Indicates an error when the state identifier is incorrect.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
