-   * @brief Q15 neural network activation function using direct table look-up
-   * @param[in,out]   data        pointer to input
-   * @param[in]       size        number of elements
-   * @param[in]       int_width   bit-width of the integer part, assume to be smaller than 3

-   * @return none.
-   *
-   * @details
-   * 
-   * This is the direct table look-up approach.
-   *
-   * Assume here the integer part of the fixed-point is <= 3.
-   * More than 3 just not making much sense, makes no difference with
-   * saturation followed by any of these activation functions.
