9.4. Interrupt Prioritization

Try these first

1. 1.

   What is interrupt prioritization?

   Hint

   Think about how urgent tasks are prioritized.

2. 2.

   Define interrupt vector.

   Hint

   It's like a map for the CPU's response.

3. 3.

   What is the primary function of interrupt prioritization?

   • To handle interrupts in the order they arrive
   • To determine the order of processing based on importance
   • To disable interrupts temporarily

   Hint

   Consider which tasks might need attention first.

4. 4.

   True or False: Interrupt vectors are used to manage the priority of interrupts.

   • True
   • False

   Hint

   Think about the function of a vector versus priority management.

5. 5.

   Design a priority scheme for a multi-sensor monitoring system where critical failures must be prioritized over regular data updates. Explain your design.

   Hint

   Think about what events in your system are most urgent.

6. 6.

   Evaluate a case study where improper interrupt prioritization led to system failure. What could have been done differently?

   Hint

   Search for situations in tech history where timing was crucial.
