Addressing Modes in Computer Architecture
Addressing modes are the methods used by a processor to access data from memory. The instruction MOV AX, 1234H is an example of immediate addressing mode. Let us understand the different types of addressing modes in computer architecture.
1. Register Addressing Mode
In register addressing mode, the operand is in a processor register. The instruction uses the register's name as the operand, for example, MOV AX, BX.
2. Direct Addressing Mode
In direct addressing mode, the operand is in memory, and the instruction specifies the memory location directly. The instruction uses the memory address as the operand, for example, MOV AX, [1234H].
3. Immediate Addressing Mode
In immediate addressing mode, the operand is a part of the instruction itself. The instruction uses the constant value as the operand, for example, MOV AX, 1234H.
4. Based Indexed Addressing Mode
In based indexed addressing mode, the operand is in memory, and the instruction specifies the memory location indirectly. The instruction uses a base register and an index register to calculate the memory address, for example, MOV AX, [BX+SI].
Conclusion
The instruction MOV AX, 1234H is an example of immediate addressing mode, where the operand is a part of the instruction itself. It is a simple and easy way to access data from memory.
