nrf_dsp_window_flatten_feed_f32()

uint16_t nrf_dsp_window_flatten_feed_f32	(	nrf_dsp_window_flatten_t *	p_ctx,
		const flt32_t *	p_input,
		uint16_t	num )

#include <include/nrf_edgeai/dsp/utils/data_windowing/nrf_dsp_window_flatten.h>

Feeds f32 samples to the floating-point flatten by columns window, with ordering by feature columns, e.g p_input = [x,y,z,x1,y1,z1] -> p_window = [x,x1,.., y,y1,.., z,z1,..].

Parameters

[in,out]	p_ctx	Pointer to the window context, should be initialized first nrf_dsp_window_flatten_init
[in]	p_input	Pointer to the feature sample buffer
[in]	num	Number of samples in the input buffer, num = buffer_size / p_ctx->uniq_features_num

Returns

uint16_t Number of remaining samples to collect window
