28.3.1. Program Counter

Try these first

1. 1.

   What is the main function of the Program Counter?

   Hint

   Think about how programs are executed in order.

2. 2.

   Name one advantage of multi-bus architecture.

   Hint

   Consider how multiple operations can happen at once.

3. 3.

   What is the main role of the Program Counter?

   • Contains the current instruction
   • Points to the next instruction
   • Stores data temporarily

   Hint

   Think about what helps the CPU know what to do next.

4. 4.

   True or False: A multi-bus architecture allows for faster execution of instructions compared to a single bus architecture.

   • True
   • False

   Hint

   Consider the benefits of parallel tasks.

5. 5.

   Given a single bus architecture, describe how the Program Counter might be modified to handle a branching instruction (like an 'if' statement).

   Hint

   Consider how branching affects the flow of instructions.

6. 6.

   Design a hypothetical CPU with a dual-bus system. Discuss how the Program Counter interacts with both buses when executing a loop.

   Hint

   Think about how parallel processes can enhance performance in loops.
