nrf_dsp_zcr_i8_s()

int16_t nrf_dsp_zcr_i8_s	(	const int8_t *	p_input,
		uint16_t	num,
		size32_t	stride )

#include <include/nrf_edgeai/dsp/statistic/nrf_dsp_zcr.h>

Counts Zero-crossing rate of a INT8 fixed-point vector ​​using values ​​in increments of 'stride'.

Parameters

[in]	p_input	Pointer to the input vector
[in]	num	Number of samples with 'stride' in input vector
[in]	stride	Vector element offset stride

Returns

int16_t Zero-crossing rate in the vector, multiplied by NRF_DSP_PERCENTAGE_TO_INT_FACTOR
