An addressing mode is a technique used in computer architecture to specify the location of data or instructions in memory. It determines how the processor interprets the operand of an instruction and retrieves data from memory.
There are typically 5-6 addressing modes in a computer architecture, including immediate, direct, indirect, indexed, and relative addressing modes. Some architectures may have additional modes such as base or stack addressing.
This instruction is a type of indirect addressing mode. It moves the data from the memory address stored in the combination of the base register (BX) and the offset (6) to the destination register (DX).
Different addressing modes allow for more flexibility and efficiency in programming. They enable programmers to access data and instructions in memory in different ways, depending on the requirements of the program.
The processor determines the addressing mode based on the opcode (operation code) of the instruction. Each opcode is associated with a specific addressing mode, and the processor will use the corresponding mode to retrieve the operand from memory.
