| Question 46 |
Arrange the following configuration for CPU in decreasing order of operating speeds: Hard wired control, vertical microprogramming, horizontal microprogramming.
| Hard wired control, vertical micro-programming, horizontal micro- programming. | |
| Hard wired control, horizontal micro-programming, vertical micro- programming. | |
| Horizontal micro-programming, vertical micro-programming, Hard wired control. | |
| Vertical micro-programming, horizontal micro-programming, hard wired control. |
Question 46 Explanation:
Hardwired control involves only hardware which is definitely faster than microprogramming approach.
Now between horizontal and vertical microprogramming, the signals in vertical microprogramming are in encoded form which has to be decoded first using decoder. So, horizontal microprogramming is faster than vertical microprogramming.
Now between horizontal and vertical microprogramming, the signals in vertical microprogramming are in encoded form which has to be decoded first using decoder. So, horizontal microprogramming is faster than vertical microprogramming.
