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).
