      Addressing Modes & Effective Address (EA) Visualizer

      1. Instruction Opcode
      LOAD R1, 8(R2)
      Mode: INDEXED Addressing Mode
      Base register plus index/offset value
      2. Address Resolution Unit
      DERIVATION FORMULA:
      EA = [R2] + Displacement/Offset = 0x1004 + 0x0008 = 0x100C
      Resolved EA: 0x100C
      Memory Bus Accesses: 1 cycle(s)
      3. Final Operand Fetched
      0x7777 (MEM[0x100C])
      Ideal for array and struct indexing (Array base address + index * element size).
