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.
