Most hardware is just wires. Especially since transistors shrunk down to nearly nothing. Still, the layout of something like a barrel shifter (e.g. http://www.erc.msstate.edu/mpl/distributions/scmos/images/bshift.gif http://www.erc.msstate.edu/mpl/distributions/scmos/images/bs... , from a casual search) takes its space on die, much like an adder or multiplier. It's all wires and switches.
