FIRSparseGetDlyLine

Retrieves the delay line contents from the sparse FIR filter state structure.

Syntax

IppStatus ippsFIRSparseGetDlyLine_32f(const IppsFIRSparseState_32f*
pState
, Ipp32f*
pDlyLine
);
IppStatus ippsFIRSparseGetDlyLine_32fc(const IppsFIRSparseState_32fc*
pState
, Ipp32fc*
pDlyLine
);

Parameters
pState
Pointer to the sparse FIR filter state structure.
pDlyLine
Pointer to the array holding the delay line values.
Description
This function copies the delay line values from the state structure
pState
and stores them into
pDlyLine
. The destination array
pDlyLine
contains samples in the reverse order as compared to the order of samples in the source vector.
Before calling
ippsFIRSparseGetDlyLine
, 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.
