Q. Define the ADDRESSING MODES?
The elementary set of operands in 8086 can reside in memory, register and immediate operand. How can these operands be retrievedby various addressing modes? The answer to the question above is provided in the subsequent sub-section. Large number of addressing modes assists in addressing complex data structures with ease. A number of specific Terms and registers roles for addressing:
Base register (BX, BP): These registers are employed for pointing to base of a stack, array etc.
Index register (SI, DI): These registers are employed as index registers in data and/or extra segments.
Displacement: It signifies offset from the segment address.
Addressing modes of 8086

Description
Direct
Effective address is the displacement of memory variable.
Register Indirect
Effective address is the contents of a register.
[BX]
[SI]
[DI]
[BP]
Based
Effective address is the sum of a base register and a displacement.
LIST[BX]
(OFFSET LIST + BX)
[BP + 1]
Indexed
Effective address is the sumof an index register and a displacement.
LIST[SI]
[LIST +DI]
[DI + 2]
Based Indexed
Effective address is the sum of a base and an index register.
[BP + DI]
Based Indexed with
displacement
Effective address is the sum of a base register, an index register, and a displacement.
[BX + SI + 2]
Define addressing modes. The dissimilar ways in which the location of an operand is specified in an instruction are referred to as addressing modes.
