6.4.2. Reducing Power Consumption

Try these first

1. 1.

   Define power gating in your own words.

   Hint

   Think of which parts you could switch off when not in use.

2. 2.

   What does test pattern compression achieve?

   Hint

   Remember, less data to move generally means less power.

3. 3.

   What is the main purpose of power gating?

   • To reduce complexity
   • To save energy
   • To increase performance

   Hint

   Think about why we'd want to turn off parts of a system.

4. 4.

   Test pattern compression involves _____.

   • True
   • False

   Hint

   Is it about using less data or more?

5. 5.

   Evaluate how the integration of all three techniques can alter the performance and energy profile of a system.

   Hint

   Consider both performance metrics and energy savings.

6. 6.

   Develop a detailed proposal outlining a testing procedure using all discussed power-saving techniques for a new embedded system.

   Hint

   Focus on integrating the concepts logically for maximum efficiency.
