ARM Architecture - Power Modes
Which syntax correctly describes the term for turning off the clock signal to parts of a processor to save power?
Which syntax correctly describes the term for turning off the clock signal to parts of a processor to save power?
easy📝 Factual Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Define clock gating
Clock gating means stopping the clock signal to parts of a processor to reduce switching activity and save power.Step 2: Match the term to the description
Power gating turns off power supply, frequency scaling changes speed, voltage boosting increases voltage, so clock gating fits best.Final Answer:
Clock gating -> Option AQuick Check:
Clock gating = Turning off clock signal [OK]
Quick Trick: Clock gating stops clock signals to save power [OK]
Common Mistakes:
- Mixing power gating with clock gating
- Confusing frequency scaling with clock gating
- Thinking voltage boosting saves power
