Wrapper function to pick the right optimized s16 depthwise convolution function.

Parameters:

  • ctx – [inout] Function context (e.g. temporary buffer). Check the function definition file to see if an additional buffer is required. Optional function {API}_get_buffer_size() provides the buffer size if required. The caller is expected to clear the buffer, if applicable, for security reasons.

  • dw_conv_params – [in] Depthwise convolution parameters (e.g. strides, dilations, pads,…) dw_conv_params->dilation is not used. Range of dw_conv_params->input_offset : Not used Range of dw_conv_params->output_offset : Not used

  • quant_params – [in] Per-channel quantization info. It contains the multiplier and shift values to be applied to each output channel

  • input_dims – [in] Input (activation) tensor dimensions. Format: [H, W, C_IN] Batch argument N is not used and assumed to be 1.

  • input_data – [in] Input (activation) data pointer. Data type: int16

  • filter_dims – [in] Filter tensor dimensions. Format: [1, H, W, C_OUT]

  • filter_data – [in] Filter data pointer. Data type: int8

  • bias_dims – [in] Bias tensor dimensions. Format: [C_OUT]

  • bias_data – [in] Bias data pointer. Data type: int64

  • output_dims – [in] Output tensor dimensions. Format: [1, H, W, C_OUT]

  • output_data – [inout] Output data pointer. Data type: int16

Returns:

The function returns ARM_CMSIS_NN_SUCCESS - Successful completion.
