Question 1.
Define Clock Gating in your own words.
Show hintHide hint
Think about the clock signal's role in circuit operation.
Question 2.
What does DVFS stand for?
Show hintHide hint
Recall the acronym and what it represents in terms of circuit adjustments.
3Question 3.
What technique reduces dynamic power by disabling clock signals of unused blocks?
- Power Gating
- Clock Gating
- MTCMOS
Show hintHide hint
Focus on the role of the clock in circuit function.
4Question 4.
True or False: Static power dissipation occurs only when the circuit is actively switching.
- True
- False
Show hintHide hint
Remember that components still draw some power when idle.
Question 5.
A circuit uses 100mW when fully active, and clock gating allows for a 40% reduction during idle states. Calculate the new power consumption during idle.
Show hintHide hint
Use the percentage reduction to find out how much power can be saved.
Question 6.
Discuss the implications of using outdated techniques (like DVFS) in modern high-performance applications that demand consistent performance and explain how designers might need to pivot.
Show hintHide hint
Consider the balance between performance and power when discussing alternatives.
