Question 1.
What is DVFS?
Show hintHide hint
Think about how voltage and frequency changes affect power.
Question 2.
What is the formula for calculating dynamic power?
Show hintHide hint
Remember the variables: alpha, capacitance, voltage, and frequency.
3Question 3.
What does DVFS stand for?
- Dynamic Voltage and Frequency Scaling
- Dynamic Variable and Frequency Sensing
- Direct Voltage and Frequency Scaling
Show hintHide hint
Focus on the relationship with voltage and frequency.
4Question 4.
True or False: Lowering Vdd always results in better performance.
- True
- False
Show hintHide hint
Consider the implications of reduced voltage levels.
Question 5.
If a system operates at 1.0V with a capacitance of 3pF and a frequency of 1.5GHz. What would the dynamic power consumption be?
Show hintHide hint
Perform the calculations step by step, starting with squared voltage.
Question 6.
Discuss the impact of implementing DVFS in a high-performance computing setting. What challenges might arise?
Show hintHide hint
Examine both sides: energy savings versus system stability and performance.
