Question 1.
What does DVFS stand for?
Show hintHide hint
Think about voltage and performance balancing.
Question 2.
What is the purpose of Clock Gating?
Show hintHide hint
Consider what happens when parts of the circuit are not actively processing data.
3Question 3.
What technique adjusts voltage and frequency based on workload?
- Multi-Vt Design
- Clock Gating

Show hintHide hint
Think of how computers adapt to different tasks.
4Question 4.
True or False: Clock Gating is used to save power by shutting down unused parts of the circuit.
- True
- False
Show hintHide hint
Consider how an inactive light consumes less energy.
Question 5.
