Signal Initialization Functions

Functions that provide functionality of initialization signal like: set, zero or copy other signal.

Signal Set

Set

The set of set initialization operations available in the library.

Set

Set methods for 1D vectors of various types.

The copy methods operate on vector data given as a pointer to the underlying data-type (e.g. 8-bit vectors would be passed as pointers to Npp8u type) and length of the vectors, i.e. the number of items.

NppStatus nppsSet_Ctx(NppDataType eSrcDstType, const void *pValue, void *pDst, size_t nLength, NppStreamContext nppStreamCtx)

Vector set method.

Supported data types include NPP_8U, NPP_8S, NPP_16U, NPP_16S, NPP_32U, NPP_32S, NPP_64S, NPP_32F, NPP_64F.

Parameters

eSrcDstType – Signal Data Type.
pValue – Host memory pointer to eSrcDstType Value used to initialize the vector pDst.
pDst – Destination Signal Pointer.
nLength – Signal Length.
nppStreamCtx – Application Managed Stream Context.

Returns

Signal Zero

Zero

The set of zero initialization operations available in the library.

Signal Copy

Copy

The set of copy initialization operations available in the library.

Copy

Copy methods for various type signals.

Copy methods operate on signal data given as a pointer to the underlying data-type (e.g. 8-bit vectors would be passed as pointers to Npp8u type) and length of the vectors, i.e. the number of items.

NppStatus nppsCopy_Ctx(NppDataType eSrcDstType, const void *pSrc, void *pDst, size_t nLength, NppStreamContext nppStreamCtx)

Vector copy method Supported data types include NPP_8U, NPP_8S, NPP_16U, NPP_16S, NPP_32U, NPP_32S, NPP_64S, NPP_32F, NPP_64F.

Parameters

eSrcDstType – Signal Data Type.
pSrc – Source Signal Pointer.
pDst – Destination Signal Pointer.
nLength – Signal Length.
nppStreamCtx – Application Managed Stream Context.
