17.3. Branching Based on Sign Flag

Try these first

1. 1.

   Define the term 'Program Counter'.

   Hint

   This is critical for understanding instruction flow.

2. 2.

   What does the sign flag indicate?

   Hint

   Think about positive and negative values.

3. 3.

   What does the sign flag represent?

   • Zero value
   • Negative value
   • Positive value

   Hint

   This value helps decide branching.

4. 4.

   A jump instruction modifies which counter?

   • True
   • False

   Hint

   Consider if jumps affect the next instruction.

5. 5.

   Explain the importance of branching in programming logic. How might incorrect flag evaluation impact a program's outcome?

   Hint

   Consider scenarios where decisions dictate program flow.

6. 6.

   Analyze the role of control signals during a jump instruction. How do they affect the operation of the CPU?

   Hint

   Think about the CPU as a conductor, directing its orchestra based on the signals given.
