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:

  1. The same width of the input tensor
  2. The same height of the input tensor
  3. 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 does not involve any arithmetic operation
Parameters
[in]inputPointer to input tensor
[in]input_xWidth of input tensor
[in]input_yHeight of input tensor
[in]input_zChannels in input tensor
[in]input_wBatch size in input tensor
[out]outputPointer to output tensor
[in]offset_wThe offset on the W axis to start concatenating the input tensor It is user responsibility to provide the correct value
Returns
None
