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 two 16-bit operands. How long does it take to fetch the operands? Give the range of possible answers. Assume a clocking rate of 4 MHz and no wait states.
