摘要： Addressing memory includes receiving a first operand to a memory addressing operator, receiving a second operand to the memory addressing operator, performing sign extension on the first operand to provide a sign-extended operand, shifting the sign-extended operand to provide a shifted, sign-extended operand, and adding the shifted, sign-extended operand to the second operand. The second operand has a different bit length than the first operand.
