Try these first

1. 1.

   What is a microinstruction?

   Hint

   Think about what the CPU executes.

2. 2.

   What does the control bus do?

   Hint

   Consider paths of communication.

3. 3.

   What function do microinstructions serve in a CPU?

   • A. They define device protocols
   • B. They are the smallest operational units
   • C. They manage memory allocation

   Hint

   Think about the smallest command the CPU can process.

4. 4.

   True or False: The control unit only uses internal signals to operate.

   • True
   • False

   Hint

   Consider interactions with memory and I/O.

5. 5.

   Design a scenario where a CPU faces a race condition due to timing mismanagement of control signals. Explain how it happened, and propose a solution.

   Hint

   Focus on how synchronization issues arise in operation timing.

6. 6.

   Analyze how failure in flag signaling could impact the control unit's decision-making during a conditional jump scenario.

   Hint

   Consider the result of previous operations affecting current decisions.
