| 26 | They are optimized by using word alignment. This will work | |
| 27 | fine if both source and destination are aligned on the same | |
| 28 | boundary. However, if they are aligned on different boundaries | |
| 29 | shifts will be necessary. This might result in bad performance | |
| 30 | on MicroBlaze systems without a barrel shifter. | |
