³   So, the conclusion is that 32 bits CAN be slower, but only if you're
³ multiplying something that really needs 32bits to be represented.  The
³ thing is, if you tried to do the same multiplication using more than one
³ 16 bit MUL, it would take longer.  Depending on how you look at it, 32
³ bits is faster AND slower. :)

Well, but, I think part of the problem is using a 16-bit integer in an
otherwise 32-bit program makes it necessary to change a couple of things
on the processor before and after handling it, each time.... which is
where the extra cycles come in...
