Question 1
Marks : +2 | -2
Pass Ratio : 100%
________ are the different type/s of generating control signals.
Micro-programmed
Hardwired
Micro-instruction
Both Micro-programmed and Hardwired
Explanation:
The above is used to generate control signals in different types of system architectures.
Question 2
Marks : +2 | -2
Pass Ratio : 100%
The End signal is generated using, End = T7.ADD + T5.BR + (T5.N+ T4.-N).BRN…

None.
Question 3
Marks : +2 | -2
Pass Ratio : 100%
The benefit of using this approach is ________
It is cost effective
It is highly efficient
It is very reliable
It increases the speed of operation
Explanation:
None.
Question 4
Marks : +2 | -2
Pass Ratio : 100%
The type of control signal is generated based on ________
contents of the step counter
Contents of IR
Contents of condition flags
All of the mentioned
Explanation:
Based on the information above the type of control signal is decided.
Question 5
Marks : +2 | -2
Pass Ratio : 100%
The disadvantage/s of the hardwired approach is ________
It is less flexible
It cannot be used for complex instructions
It is costly
less flexible & cannot be used for complex instructions
Explanation:
The more complex the instruction set less applicable to a hardwired approach.
Question 6
Marks : +2 | -2
Pass Ratio : 100%
The name hardwired came because the sequence of operations carried out is determined by the wiring.
True
False
Explanation:
In other words hardwired is another name for Hardware Control signal generator.
Question 7
Marks : +2 | -2
Pass Ratio : 100%
What does the hardwired control generator consist of?
Decoder/encoder
Condition codes
Control step counter
All of the mentioned
Explanation:
The CU uses the above blocks and IR to produce the necessary signal.
Question 8
Marks : +2 | -2
Pass Ratio : 100%
What does the end instruction do?
It ends the generation of a signal
It ends the complete generation process
It starts a new instruction fetch cycle and resets the counter
It is used to shift the control to the processor
Explanation:
It is basically used to start the generation of a new signal.
Question 9
Marks : +2 | -2
Pass Ratio : 100%
The Zin signal to the processor is generated using, Zin = T1+T6 ADD + T4.BR…
True
False
Explanation:
The signal is generated using the logic of the formula above.
Question 10
Marks : +2 | -2
Pass Ratio : 100%
What does the RUN signal do?
It causes the termination of a signal
It causes a particular signal to perform its operation
It causes a particular signal to end
It increments the step counter by one
Explanation:
The RUN signal increments the step counter by one for each clock cycle.
