Registers $R4$ contains the decimal number $2000$. If the addressing mode used is $12$($R4$) (Base plus Displacement addressing mode), what is the Effective Address ($EA$)?

The Base plus Displacement addressing mode works like this:

$$
EA=\text { Displacement }+[\text { BaseRegister }]
$$

  • Displacement $=12$
  • Base Register $R4$ $=2000$

So,

$$
EA=12+2000=2012
$$


Final Answer: $2012$
