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