curprev 22:3122:31, 20 January 2020‎ Guy Harris talk contribs‎ 23,003 bytes −24‎ Some processors might 1) support unaligned accesses and 2) not impose a penalty for them (I think newer x86 processors do), but not all processors do. And byte addressing isn't required - you could still pack two 16-bit values in a 32-bit word on a machine with word addressing, with a load doing unpacking and a store doing packing, using multiple instructions. undo
curprev 18:4818:48, 20 January 2020‎ Guy Harris talk contribs‎ 23,027 bytes −37‎ OK, better example. (Yes, that's possible even on machines that require alignment of multi-byte values integral/address values - loading the unaligned value would require multiple instructions, but it can be done.) undo
