nrf_dsp_rms_i16_s()

int32_t nrf_dsp_rms_i16_s	(	const int16_t *	p_input,
		uint16_t	num,
		size32_t	stride,
		nrf_dsp_stat_ctx_i16_t *	p_ctx )

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

Calculate RMS value of a INT16 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
[in]	p_ctx	Optional pointer to the statistics context, this function will use p_ctx->value.tss for calculation if it exist

Returns

int32_t RMS value of the vector
