Can a 32-bit processor work with a 64-bit size word?
Just what makes a processor a 32-bit processor?
And what would 64-bit word/32-bit halfword mean in the context?
There are processors allowing a single instruction to read more than one &quot;memory cell&quot;, with documentation more or less readily available. The DEC VAX is notorious for having quad- and octaword accesses (a word being half the width of the general purpose registers (and data bus of early implementations)…).
There are processors with the width of the data bus smaller than a GPR. The Motorola 68000 was dubbed a 16-bit CPU - with 32 bit GPRs from the start. Then, the were Intel 8088, 68008 with a data bus a quarter in width compared to its GPRs, …
There are (memory) buses that allow locking of consecutive transfers.
There are buses and memory interfaces (on processing units as well as on memory devices) providing for burst transfers.
