Memory Addressing Modes

What this computer architecture addressing modes question tests

This question probes your understanding of register-relative addressing, a fundamental memory access pattern in CPU design. It asks you to identify and explain the specific hardware components that combine to produce an effective memory address during instruction execution.

Interviewers ask this to verify that you understand how processors translate high-level memory references into concrete bus transactions. The question rewards precision: you need to name the actual components involved and explain their roles in the calculation, not just list them.

• Address calculation hardware and ALU involvement
• Offset encoding and register values
• How addressing modes reduce instruction size and improve code density
