Layer 7: Interactive Laboratory
Interactive Simulator
COA • SIMULATIONC Pointers, Memory Addresses & Dereferencing Simulator
COA • CPU ARCHITECTUREOperand Fetch & Memory Dereference
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).
