Consider a hypothetical processor with an instruction of type, which during execution reads a 32-bit word from memory and stores it in a 32-bit register. The effective address of the memory location is obtained by the addition of a constant 20 and the contents of register. Which of the following best reflects the addressing mode implemented by this instruction for the operand in memory?
  • a)
    Immediate addressing
  • b)
    Register addressing
  • c)
    Register Indirect Scaled Addressing
  • d)
    Base Indexed Addressing
Correct answer is option 'D'. Can you explain this answer?

Addressing Mode Implemented by the Instruction

The addressing mode implemented by the instruction is Base Indexed Addressing.

Explanation

- In this hypothetical processor, the instruction reads a 32-bit word from memory and stores it in a 32-bit register.
- The effective address of the memory location is obtained by the addition of a constant 20 and the contents of a register.
- This addressing mode is known as Base Indexed Addressing, where the base address is stored in a register and an index value (in this case, the constant 20) is added to it to get the effective address.

Comparison with Other Addressing Modes

Let's briefly discuss the other addressing modes to understand why they are not suitable for this scenario.

1. Immediate Addressing: In immediate addressing, the operand value is directly specified in the instruction itself. However, in this case, the operand value is obtained from memory, so immediate addressing is not applicable.

2. Register Addressing: In register addressing, the operand value is stored in a register. However, in this case, the operand value is obtained from memory, so register addressing is not applicable.

3. Register Indirect Scaled Addressing: In register indirect scaled addressing, the effective address is obtained by adding a scaled offset to the contents of a register. However, in this case, the offset is a constant value of 20, not a scaled offset. Therefore, register indirect scaled addressing is not applicable.

4. Base Indexed Addressing: In base indexed addressing, the effective address is obtained by adding an index value to the contents of a base register. This matches the scenario described in the question, where a constant 20 is added to the contents of a register to obtain the effective address. Hence, base indexed addressing is the correct addressing mode for this instruction.

Conclusion

The addressing mode implemented by the instruction for the operand in memory is Base Indexed Addressing because it involves adding a constant 20 to the contents of a register to obtain the effective address.
