addressing modes in 8086 with example
What is addressing mode in 8086 microprocessor?
In the 8086 microprocessor, in order to perform an operation on data, an instruction is given to the microprocessor. The data on which the operation is performed are called operands. Addressing mode represents a method of assigning the address of the source of data or operand to the instruction given to the microprocessor.
What are the different types of addressing modes?
Displacement or direct mode – In this type of addressing mode the effective address is directly given in the instruction as displacement. Register indirect mode – In this addressing mode the effective address is in SI, DI or BX. Based indexed mode – In this the effective address is sum of base register and index register.
