Block Diagram 8086 Microprocessor Architecture. The pre fetched instruction are held for eu. It is available in three versions.
The function of both of these two units is that they perform their operation together. 80186 is a 16 bit microprocessor with 16 bit data bus and 20 bit address bus. Except in case of jump call where the queue is dumped and reloaded.
Write the data to the port.
Internal block diagram of 8086 microprocessor. 1 bus interface unit and 2 execution unit they are explained below. As we see the whole block diagram is divided into two parts. Except in case of jump call where the queue is dumped and reloaded.
