6 sample questions

Question 1.
What is the purpose of control signals in CPU functionality?
Show hintHide hint
Think about how commands are sent to different parts of the CPU.
Question 2.
Define what a finite state machine (FSM) is.
Show hintHide hint
Consider how instructions change states in a program.
3Question 3.
What does the MFC signal indicate?
- The memory operation is complete
- The CPU is idle
- The instruction is being executed
Show hintHide hint
Think of MFC as a 'green light' for memory operations.
4Question 4.
True or False: Conditional jumps occur regardless of flag status.
- True
- False
Show hintHide hint
Recall how flags can enable or disable certain operations.
Question 5.
Devise a set of control signals needed for a CPU to execute both an ADD and a conditional jump operation together, detailing how you would ensure synchronization.
Show hintHide hint
Consider how flags play into this and whether checks are required.
Question 6.
Explore the implications of having a faulty signal in an FSM controlling conditional jumps. What might happen if the flag indicating a ‘zero’ condition fails to register?
Show hintHide hint
Reflect on how critical flags are for determining control flows.
