6 sample questions

Question 1.
What is power gating used for?
Show hintHide hint
Think about why a computer uses less energy when it's not fully active.
Question 2.
Describe a dual-edge triggered flip-flop.
Show hintHide hint
Consider how flip-flops interact with clock signals.
3Question 3.
What is the primary goal of implementing power gating in CPUs?
- Reduce heat generation
- Conserve energy
- Increase performance
Show hintHide hint
Consider what's happening when the CPU is inactive.
4Question 4.
True or False: Dual-edge triggered flip-flops can only activate on the rising edge of a clock signal.
- True
- False
Show hintHide hint
Think about what 'dual-edge' implies.
Question 5.
Evaluate the design choice of using dual-edge triggered flip-flops versus traditional flip-flops in a mobile CPU. How could this affect battery life?
Show hintHide hint
Consider how often the flip-flops will need to switch states.
Question 6.
Propose a new CPU feature that could work in tandem with power gating to improve efficiency further. Justify your choice.
Show hintHide hint
Think about how user interaction with the device might influence CPU demand.
