Question 1.
What is clock gating?
Show hintHide hint
Think about how you would save electricity at home.
Question 2.
What does dynamic power consumption refer to?
Show hintHide hint
Focus on the term ‘dynamic’ in the context of circuit behavior.
3Question 3.
What is the primary function of clock gating?
- To increase power
- To reduce power
- To manage frequencies
Show hintHide hint
Think about energy conservation techniques.
4Question 4.
True or False: Gate-level power optimization involves increasing the number of switching events.
- True
- False
Show hintHide hint
Consider the goal of minimizing energy consumption.
Question 5.
You are tasked with designing a VLSI circuit for a battery-operated device. Propose a clock gating strategy that could save power and explain your rationale.
Show hintHide hint
Think about which components in your device might remain idle during operation.
Question 6.
A circuit consumes 80 mw when fully active. If the implementation of gate-level power optimization reduces the switching activity by 40%, calculate the new power consumption and provide a brief explanation.
Show hintHide hint
Focus on understanding the percentage impacts on overall power consumption.
