  • input1_dims – [in] pointer to input tensor 1 dimensions

  • input2_data – [in] pointer to input tensor 2

  • input2_dims – [in] pointer to input tensor 2 dimensions

  • input1_offset – [in] offset for input 1. Range: -127 to 128

  • input1_mult – [in] multiplier for input 1

  • input1_shift – [in] shift for input 1

  • input2_offset – [in] offset for input 2. Range: -127 to 128

  • input2_mult – [in] multiplier for input 2

  • input2_shift – [in] shift for input 2

  • left_shift – [in] left shift applied to the result

  • output_data – [out] pointer to output tensor

  • output_dims – [in] pointer to output tensor dimensions

  • out_offset – [in] output offset. Range: -128 to 127

  • out_mult – [in] output multiplier

  • out_shift – [in] output shift

  • out_activation_min – [in] minimum value to clamp output to. Min: -128

  • out_activation_max – [in] maximum value to clamp output to. Max: 127
