  • input_1_offset – [in] offset for input 1. Not used.

  • input_2_offset – [in] offset for input 2. Not used.

  • output – [out] pointer to output vector

  • out_offset – [in] output offset. Not used.

  • out_mult – [in] output multiplier

  • out_shift – [in] output shift

  • out_activation_min – [in] minimum value to clamp output to. Min: -32768

  • out_activation_max – [in] maximum value to clamp output to. Max: 32767

  • block_size – [in] number of samples

Returns:

The function returns ARM_CMSIS_NN_SUCCESS
