17.1.2. Control Signals and Bus Architecture

Try these first

1. 1.

   Define the term 'Program Counter'.

   Hint

   Think about where the CPU looks to find what to do next.

2. 2.

   What does the zero flag indicate?

   Hint

   Consider how conditions are checked before making decisions.

3. 3.

   What does the control signal do in a CPU?

   • A. Directs data movements and operations
   • B. Stores data temporarily
   • C. Increases the clock speed

   Hint

   Consider the role of traffic signals in directing traffic.

4. 4.

   Conditional jumps rely on specific flags. True or False?

   • True
   • False

   Hint

   Think of how conditions influence decisions when executing code.

5. 5.

   How would you design a CPU that successfully manages nested subroutine calls with their corresponding returns, ensuring that each return goes back to the correct instruction?

   Hint

   Consider stack operations and how LIFO (Last In First Out) works.

6. 6.

   Evaluate the effectiveness of conditional vs. unconditional jumps in program execution. Provide an example scenario of each.

   Hint

   Think about programming constructs where you make decisions based on conditions versus just moving to a set location.
