11.6.2. Low Power Consumption

Try these first

1. 1.

   What is low power consumption?

   Hint

   Think about why we want to save battery life.

2. 2.

   Name one method to achieve low power consumption.

   Hint

   Think about how devices can manage their activity.

3. 3.

   What is the main purpose of sleep modes?

   • To enhance performance
   • To reduce power consumption
   • To increase responsiveness

   Hint

   Think about how devices can run longer on battery.

4. 4.

   True or False: Interrupt-driven I/O requires the CPU to constantly check for input.

   • True
   • False

   Hint

   Remember how interrupts work.

5. 5.

   Design a power-efficient embedded system for a remote sensor. Outline the low power strategies you would implement.

   Hint

   Consider how real-world sensors operate.

6. 6.

   Evaluate a scenario where a device is both actively processing data and needs to save energy. What dual strategies can you employ?

   Hint

   Think about the balance between activity and rest.
