Allows turn on optimalized library function (memcpy and memmove). |
|
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. |
