In 8086 why even address location takes two bus cycles whereas odd address location takes only one..

Answer / dhaval pipalia

The 8086 takes two cycles to fetch words from an odd address
because the Bus Interface Unit (BIU) actually only deals
with words, which are two bytes at an even address.

If you perform an operation on a byte, the BIU will do a
word operation, but it will leave the other byte alone.

If you perform a word operation at an even address, the BIU
can do the operation in one cycle.

If the word, however, is at an odd address, the BIU must use
two cycles, leaving the respective "other" byte alone in
each case. For performance sake, always align your data with
the bus design.
