| Question 9 |
A CPU has 24-bit instructions. A program starts at address 300 (in decimal). Which one of the following is a legal program counter (all values in decimal)?
| 400 | |
| 500 | |
| 600 | |
| 700 |
Question 9 Explanation:
The instruction is of 24 bits or 3 bytes. Now the program starts at address 300 and the next will be 303 then, 306, then 309 and so on.
So finally we can say that the values in the program counter will always be the multiple of 3.
Hence, option (C) is correct.
So finally we can say that the values in the program counter will always be the multiple of 3.
Hence, option (C) is correct.
