 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.
