9.5.1. Vectored Interrupts

Try these first

1. 1.

   What is a vectored interrupt?

   Hint

   Think of it as a map for the CPU to find the right code.

2. 2.

   What is the purpose of an interrupt vector table?

   Hint

   It's like a phone book for the CPU.

3. 3.

   What is the main benefit of using vectored interrupts?

   • Slower response times
   • Faster ISR execution
   • More complex coding

   Hint

   Think about how navigation changes with clear directions.

4. 4.

   True or False: Vectored interrupts can save processing cycles.

   • True
   • False

   Hint

   Consider how shortcuts save time.

5. 5.

   How would implementing vectored interrupts affect the performance of a real-time application that previously relied on non-vectored interrupts? Discuss in terms of speed and task management.

   Hint

   Think about how critical time-sensitive tasks need instantaneous access.

6. 6.

   Design a simple system that uses vectored interrupts. Describe how you would structure the interrupt vector table and handle multiple interrupt sources within it.

   Hint

   Consider how organized a system needs to be to handle many inputs smoothly.
