We will study Intel 8086 which is the start of the 80x86 family tree – All programming registers are 16-bit 16 bit data bus and 20 bit address bus – 16-bit data
Part
– Interrupt mechanism (later) • Intel 8086: start of the 80x86 family tree – All registers: 16-bit – 16
Part
The registers inside the 8086 are all 16 bits They are split up All of the general purpose registers can be treated as a 16 bit quantity or as two 8 bit quantities

The 8086 has a total of fourteen 16-bit registers including a 16 bit register called the status register, with 9 of bits implemented for status and control flags Most of
Lecture
If you use a data register as an 8 bit register, you cannot use its 16 bit parent at the same time The four index registers can be used for arithmetic operations but
Registers
DI - Destination index register • BP - base pointer • SP - stack pointer Above four 16-bit registers can also be used as
