Syntax

public static class ZeroCrossing

Methods

nppsZeroCrossing_16s32f(CUdeviceptr, Int32, CUdeviceptr, NppsZCType, CUdeviceptr)

16-bit signed short integer zero crossing method, return value is 32-bit floating point.

Declaration

public static NppStatus nppsZeroCrossing_16s32f(CUdeviceptr pSrc, int nLength, CUdeviceptr pValZC, NppsZCType tZCType, CUdeviceptr pDeviceBuffer)

Parameters

Type	Name	Description
CUdeviceptr	pSrc	Source signal pointer.
System.Int32	nLength	Signal length. Tells the primitive how many of the signal’s samples starting from the given data pointer are to be processed..
CUdeviceptr	pValZC	Pointer to the output result.
NppsZCType	tZCType	Type of the zero crossing measure: nppZCR, nppZCXor or nppZCC.
CUdeviceptr	pDeviceBuffer	Pointer to the required device memory allocation.

Returns

Type	Description
NppStatus	NullPointerError, AlignmentError, SizeError.
