In some machines, accesses to objects larger than a byte must be aligned . An access to an object of size s bytes at byte address A is aligned if A mod s = 0.
|Object Addressed||Aligned at Byte Offset||Misaligned at Byte Offset|
Misalignment causes hardware complications, since the memory is typically aligned on a word boundary. A misaligned memory access will, therefore, take multiple aligned memory references.
Even if data is aligned, supporting byte and halfword
accesses requires an alignment network to align bytes and halfwords in
