You must align these as follows:
•
•
•
Memory systems are expected to support all data types. In particular, the system must
support subword writes without corrupting neighboring bytes in that word.
words, 32-bit
halfwords, 16-bit
bytes, 8-bit.
word quantities must be aligned to four-byte boundaries
halfword quantities must be aligned to two-byte boundaries
byte quantities can be placed on any byte boundary.
