8.7. Performance Considerations

Try these first

1. 1.

   Define latency in your own words.

   Hint

   Think about how long it takes for a light to turn on after you press a switch.

2. 2.

   What is data throughput?

   Hint

   Consider how fast your internet connection is.

3. 3.

   What is latency?

   • The speed of data processing
   • Time delay in system response
   • Power use of the device

   Hint

   Relate this to pressing a button and expecting a light to turn on.

4. 4.

   True or False: High data throughput implies efficient data processing.

   • True
   • False

   Hint

   Think of it as a fast freeway for data.

5. 5.

   Design an embedded system that requires both low latency and high-thoroughput. Discuss trade-offs.

   Hint

   Think about how real-time requirements might shape your design choices.

6. 6.

   Evaluate how an increase in GPIO activity can lead to higher power consumption and lower data throughput.

   Hint

   Relate it to bus congestion when many vehicles try to use the same road.
