| Question 33 |
Which of the following is/are true of the auto-increment addressing mode?
- I. It is useful in creating self-relocating code
II. If it is included in an Instruction Set Architecture, then an additional ALU is required for effective address calculation
III. The amount of increment depends on the size of the data item accessed
| I only | |
| II only | |
| III Only | |
| II and III only |
Question 33 Explanation:
I. Self relocating code always takes some address in memory. So auto-increment mode is not used for self relocating code. Hence this statement is wrong.
II. An additional ALU is not necessary for auto-increment. So this statement is wrong.
III. In auto-increment addressing mode the address where next data block to be stored is generated automatically depending upon the size of single data item required to store. This is based on pointer arithmetic. So this statement is true.
Hence option C is the answer.
II. An additional ALU is not necessary for auto-increment. So this statement is wrong.
III. In auto-increment addressing mode the address where next data block to be stored is generated automatically depending upon the size of single data item required to store. This is based on pointer arithmetic. So this statement is true.
Hence option C is the answer.
