| 50 | * |
| 51 | * @attention The inputs and output data types need to be passed at compile time using -DDATA_TYPE_IN1, -DDATA_TYPE_IN2 and -DDATA_TYPE_OUT: |
| 52 | * e.g. -DDATA_TYPE_IN1=uchar -DDATA_TYPE_IN2=ushort -DDATA_TYPE_OUT=short |
| 53 | * @attention The data_type of the intermediate result of the multiplication should passed as well using -DDATA_TYPE_RES. |
| 54 | * e.g. If one of inputs is S16 -DDATA_TYPE_RES=int should be passed else -DDATA_TYPE_RES=short. |
