Some I/O buses require that data sent across them be aligned properly for the receiver. Other buses do not have this requirement, which means that the receiver must perform re-alignment to store data if the alignment does not match. Bus interface hardware must perform alignment of bytes to avoid violating this requirement without requiring wasteful copying of data by the processor. Whether the alignment is done in the sender or receiver is immaterial to this design. (Image Omitted)
