The addressing mode which makes use of in-direction pointers is ______...
Indirect Addressing Mode:
Indirect addressing mode is a type of addressing mode in computer architecture that uses in-direction pointers to access memory locations. In this mode, the operand of an instruction specifies a memory address where the actual data is stored.
Key points:
- Indirect addressing mode involves using a memory address to access another memory address where the desired data is stored.
- It requires an additional memory access to retrieve the actual data, which can impact the performance of the system.
- Indirect addressing mode is commonly used in situations where the exact memory location of the data is not known in advance.
Example:
Consider a scenario where a register R1 contains a memory address pointing to the actual memory location of the data. In this case, the instruction would have the format "LOAD R2, (R1)" where R1 contains the address of the data to be loaded into R2.
Conclusion:
Indirect addressing mode is a useful addressing mode that allows for flexibility in accessing memory locations by using in-direction pointers. It is commonly used in various computer architectures to facilitate efficient data retrieval and manipulation.
