Function arm_convolve_s4_get_buffer_size

Function Documentation

int32_t arm_convolve_s4_get_buffer_size(const cmsis_nn_dims *input_dims, const cmsis_nn_dims *filter_dims)

Get the required buffer size for s4 convolution function.

The dimensions and the byte count are both checked here, so an out-of-range shape returns -1 on every build target rather than a wrapped size.

Parameters:
  • input_dims[in] Input (activation) tensor dimensions. Format: [N, H, W, C_IN]

  • filter_dims[in] Filter tensor dimensions. Format: [C_OUT, HK, WK, C_IN] where HK and WK are the spatial filter dimensions

Returns:

The function returns required buffer size in bytes, or -1 if any dimension it reads is negative or the required size would not fit in an int32_t
