- * @attention Data type can be passed using the -DDATA_TYPE compile flag, e.g. -DDATA_TYPE=float
- * @attention Vector size should be given as a preprocessor argument using -DVEC_SIZE=size. e.g. -DVEC_SIZE=16
- * @note Can only take floating point data types.
- *
- * @param[in] input_ptr Pointer to the source image. Supported data types: F16/F32
- * @param[in] input_stride_x Stride of the source image in X dimension (in bytes)
- * @param[in] input_step_x input_stride_x * number of elements along X processed per workitem(in bytes)
