9.2. Types of Interrupts

Try these first

1. 1.

   What is a hardware interrupt?

   Hint

   Think about devices that signal the CPU.

2. 2.

   What can maskable interrupts do?

   Hint

   Consider interrupt priorities.

3. 3.

   What type of interrupt cannot be disabled by the processor?

   • Maskable Interrupt
   • Non-Maskable Interrupt
   • Hardware Interrupt

   Hint

   Think about urgency.

4. 4.

   True or False: Software interrupts are generated by I/O devices.

   • True
   • False

   Hint

   Consider the source of the interrupt.

5. 5.

   Design a scenario where a CPU executes a software interrupt during high-frequency hardware interrupts.

   Hint

   Consider the demands on the CPU.

6. 6.

   Analyze the implications of ignoring a non-maskable interrupt within a real-time system.

   Hint

   Reflect on the effectiveness and safety of computing systems.
