9.2.5. Internal and External Control Signals

Try these first

1. 1.

   What is the purpose of control signals in the CPU?

   Hint

   Think about how data moves and tasks are coordinated.

2. 2.

   Name one internal control signal.

   Hint

   Consider operations performed solely inside the CPU.

3. 3.

   What do internal control signals primarily control?

   • Data flow to I/O
   • ALU operations
   • Communication with memory

   Hint

   Focus on operations that happen inside the CPU.

4. 4.

   Are control signals generated for external interactions?

   • True
   • False

   Hint

   Think about the CPU’s interaction with other components.

5. 5.

   You need to design a sequence to execute an addition operation involving a read from memory. Describe what internal and external control signals are needed and when they are activated.

   Hint

   Think about the steps needed to pull data and compute results.

6. 6.

   Create a timing diagram for the execution of a conditional jump operation based on a zero flag. Illustrate each stage clearly.

   Hint

   Remember to account for signals that depend on prior operations.
