Description

Function Documentation

void arm_concatenation_s8_w	(	const int8_t *	input,
		const uint16_t	input_x,
		const uint16_t	input_y,
		const uint16_t	input_z,
		const uint16_t	input_w,
		int8_t *	output,
		const uint32_t	offset_w
	)

i.e. offset_w = 0 for(i = 0 i < num_input_tensors; ++i) { arm_concatenation_s8_w(&input[i], ..., &output, ..., ..., offset_w) offset_w += input_w[i] }

This function assumes that the output tensor has:

The same width of the input tensor
The same height of the input tensor
The same number o channels of the input tensor

Unless specified otherwise, arguments are mandatory.

Note: This function, data layout independent, can be used to concatenate either int8 or uint8 tensors because it does not involve any arithmetic operation

Parameters

[in]	input	Pointer to input tensor
[in]	input_x	Width of input tensor
[in]	input_y	Height of input tensor
[in]	input_z	Channels in input tensor
[in]	input_w	Batch size in input tensor
[out]	output	Pointer to output tensor. Expected to be at least input_x * input_y * input_z * input_w bytes.
[in]	offset_w	The offset on the W axis to start concatenating the input tensor It is user responsibility to provide the correct value
