Question

draw & explain demultiplexing of address & bus in 8086​

Answer 1

Answer:

Data Bus: - In 8086 microprocessor Pins AD0 – AD15 are used for the data bus. ... - When the address data is sent out, the ALE is high indicating that AD0-AD15 will be used as address bus - This process of separating address and data from pins AD0-AD15 is called demultiplexing.

PLEASE MARK ME AS BRAINLIST

Explanation:

Heya there,

Here's the answer you were looking for :)

Demultiplexing is to separate 2 or more channels that have been multiplexed. Signals are typically multiplexed or combined onto one higher speed channel to efficiently use the bandwidth.

The 8086 can address 1,114,080 bytes. That does not count I/O space, it only counts memory space.

there are five addressing modes in 8086 they are : 1->direct addressing 2->Indirect addressing 3->index addressing 4->immediate addressing 5->register addressing.

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.

Hope this answer helped you!!!!!!

THANK YOU!!!!!!!
