10.1. Basic Architecture for a Single Unit Bus

Try these first

1. 1.

   What is the function of a control bus?

   Hint

   Think about how communication is managed among the CPU's parts.

2. 2.

   What do registers do?

   Hint

   Consider the role of registers during operations.

3. 3.

   What does the control bus do?

   • Transfers data
   • Sends control signals
   • Stores instructions

   Hint

   Remember its primary role in communication.

4. 4.

   True or False: Multiple components can write to the bus simultaneously.

   • True
   • False

   Hint

   Think about how coordination is achieved.

5. 5.

   Explain how a signal must be managed when transferring a value from R1 to R2 in a single unit bus architecture.

   Hint

   Visualize the bus and consider the roles of R1 and R2 carefully.

6. 6.

   Illustrate the consequences of allowing multiple outputs on a bus during a single operation.

   Hint

   Think about a crowded room where many people attempt to speak at once.
