| 49 | * @note Leftover vector size has to be passed at compile time using -DVEC_SIZE_LEFTOVER. e.g. -DVEC_SIZE=3. It is defined as the remainder between the input's first dimension and VEC_SIZE |
| 50 | * @note In case of broadcasting along the X dimension the proper preprocessor argument should be passed depending on the input (e.g. -DIS_IN1_X_BROADCASTING, -DIS_IN2_X_BROADCASTING) |

| 57 | * @note To perform saturating operation -DSATURATE has to be passed to the compiler otherwise wrapping policy will be used. |
| 58 | * @note The element-wise operation to be executed has to be passed at compile time using -DOP (e.g., -DOP=ADD) |
| 59 | * @note For QSYMM16 operations OFFSET_IN1, OFFSET_IN2 and OFFSET_OUT must be set to zero |
| 60 | * @note The data type must be passed at compile time using -DDATA_TYPE_OUT, i.e. -DDATA_TYPE_OUT=uchar |
