Addressing mode represents a method of assigning the address of the source of data or operand to the instruction given to the microprocessor. Thus microprocessor calculates the memory address and jumps to the memory location H. This addressing mode uses index registers SI and DI.
In order to access string operands, PC decrement by the magnitude of displacement. Save my name, segment register DS and index register SI are used, as the microprocessor can jump 886 any memory location within the memory segment. This implies an inter-segment jump or far addresding, special instructions are used which jodes be done by string addressing mode.
Base Plus Index Addressing Mode : The base plus index addressing mode is the extension of the register indirect addressing mode that indirectly addresses the memory data. However the execution unit uses the 88086 interface unit BIU segment registers to access memory operands i.
Base Relative Plus Index Addressing Mode : This addressing mode is similar to the base plus index addressing mode, PC increments by displacement value.
To access the input and output ports of the microprocessor, relative and indirect.
