. There are also three 16-bit segment registers (see figure) that allow the 8086 CPU to access one megabyte of memory in an unusual way. rather than concatenating the segment register with the address register, as in most processors whose address space exceeds their register size, the 8086 shifts the 16-bit segment only four bits left before adding it to the 16-bit offset (16 × segment + offset ), therefore producing a 20-bit external (or valid tive or physical) address from the 32-bit segment:

address. The segment address and offset address are sent to a part called the address divider through the internal bus. The address divider combines two 16-bit addresses into a 20-bit physical address. The address divider sends 20-bit physical addresses to the input/output control circuit through the internal bus. The Input/Output Control Circuit sends 20-bit physical addresses to the address bus. 20-bit physical address is transferred to the memory by the address bus

MoV Al, 15; set the low position to 8; MoV ah, 0; this sets the high position to 0; The value of ax is changed to 0008. The byte is counted as byte. A byte consists of 8 bits, which can be contained in 8-bit registers. Word: it is recorded as word. A word consists of two bytes. These two bytes are called the high byte and low byte of the word respectively. The address divider uses the
