Understanding Immediate Addressing Modes
Immediate addressing mode is a fundamental concept in computer architecture that allows for direct use of constant values in instructions. This addressing mode has two primary applications:
1. Loading Internal Registers with Initial Value
- Immediate addressing allows a processor to load a register with a specific constant value directly.
- For example, an instruction like `MOV R1, #5` uses immediate addressing to load the value 5 into register R1.
- This is efficient as it eliminates the need to fetch the value from memory.
2. Performing Arithmetic or Logical Operations on Immediate Data
- Immediate values can also be used in arithmetic and logical operations.
- For instance, an instruction like `ADD R1, #10` adds the immediate value 10 to the contents of register R1.
- This allows for quick computations without accessing memory, enhancing performance.
Conclusion
Given these functionalities, immediate addressing modes are versatile and can serve both purposes effectively:
- Both loading registers and performing operations are integral functions that immediate addressing can accomplish.
- Therefore, the correct answer is option 'C', indicating that immediate addressing modes can be used for either purpose.
This versatility makes immediate addressing a valuable tool in efficient programming and CPU operation.
