| Question 5 |
In ______ addressing mode, the operands are stored in the memory. The address of the corresponding memory location is given in a register which is specified in the instruction.
| Register direct | |
| Register indirect | |
| Base indexed | |
| Displacement |
Question 5 Explanation:
Register indirect: It is specified implicitly in the definition of instruction. Register indirect addressing mode, the operands are stored in the memory. The address of the corresponding memory location is given in a register which is specified in the instruction.
Index mode: The address of the operand is obtained by adding to the contents of the general register (called index register) a constant value. The number of the index register and the constant value are included in the instruction code.
Index mode: The address of the operand is obtained by adding to the contents of the general register (called index register) a constant value. The number of the index register and the constant value are included in the instruction code.
