NppStatus nppsZeroCrossing_16s32f | ( | const Npp16s * | pSrc, |
int | nLength, | ||
Npp32f * | pValZC, | ||
NppsZCType | tZCType, | ||
Npp8u * | pDeviceBuffer | ||
) |
16-bit signed short integer zero crossing method, return value is 32-bit floating point.
pSrc | Source Signal Pointer. |
nLength | Signal Length. |
pValZC | Pointer to the output result. |
tZCType | Type of the zero crossing measure: nppZCR, nppZCXor or nppZCC. |
pDeviceBuffer | Pointer to the required device memory allocation, Scratch Buffer and Host Pointer. Use nppsZeroCrossingGetBufferSize_16s32f to determine the minium number of bytes required. |
