$3\mathrm{.}16$ The Intel $8086$ is a $16-$bit processor similar in many ways to the $8-$bit $8088.$ The $8086$ uses a $16-$bit bus that can transfer $2$ bytes at a time, provided that the lower$-$order byte has an even address. However, the $8086$ allows both even$-$ and odd$-$aligned word operands. If an odd$-$aligned word is referenced, two memory cycles, each consisting of four bus cycles, are required to transfer the word. Consider an instruction on the $8086$ that involves four $16-$bit operands. How long does it take to fetch the operands? Give the range of possible answers. Assume a clocking rate of $2MHz$ and no wait states.
