9.7. Interrupts in Multitasking and Real-Time Systems

Try these first

1. 1.

   Define context switching in your own words.

   Hint

   Think about how we manage multiple tasks.

2. 2.

   What does RTOS stand for?

   Hint

   Remember what type of systems need to meet strict timing requirements.

3. 3.

   What is the primary role of interrupts in multitasking?

   • A. To handle software programs
   • B. To enable time-sensitive task execution
   • C. To increase CPU power consumption

   Hint

   Think about their role in managing various tasks.

4. 4.

   True or False: In a real-time operating system, lower-priority tasks can always interrupt higher-priority tasks.

   • True
   • False

   Hint

   Consider how priorities are structured.

5. 5.

   Design a real-time system for managing heart rate monitors and explain how interrupts will ensure timely data processing.

   Hint

   Think about monitoring systems and their urgency.

6. 6.

   Propose an algorithm that balances efficiency with response time in a multitasking environment using context switching.

   Hint

   Consider how frequently tasks should be allowed to switch.
