Try these first

1. 1.

   What is the primary role of the control unit in a CPU?

   Hint

   Think about what manages data flow.

2. 2.

   Define microinstruction.

   Hint

   It breaks down macro instructions.

3. 3.

   What does the control unit primarily generate?

   • Data Outputs
   • Control Signals
   • Memory Addresses

   Hint

   Consider what manages the CPU's internal operations.

4. 4.

   True or False: The opcode defines the operation the control unit will perform.

   • True
   • False

   Hint

   Reflect on how instructions differ.

5. 5.

   Design a timing diagram for an ADD operation in a simplistic CPU. Include control signals for the ALU and memory.

   Hint

   Identify each stage of the operation clearly.

6. 6.

   Suppose you have a simple program with a conditional jump. Describe the sequence of control signals necessary to execute this instruction.

   Hint

   Think through each decision point.
