◆ nrf_dsp_tcr_i32()

int16_t nrf_dsp_tcr_i32 ( const int32_t * p_input,
uint16_t num,
const int32_t threshold )

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

Counts Threshold-crossing rate of a INT32 fixed-point vector.

Parameters
[in]p_inputPointer to the input vector
[in]numNumber of samples in input vector
[in]thresholdThreshold value for counting crossing rate
Returns
int16_t Threshold-crossing rate in the vector, multiplied by NRF_DSP_PERCENTAGE_TO_INT_FACTOR
