2. Depending on the operand size, displacement is scaled by ×1, ×2, or ×4. For details,
The actual number of states may be increased when (1) contention occurs between
instruction fetches and data access, or (2) when the destination register of the load
instruction (memory → register) equals to the register used by the next instruction.
