ARM Architecture - Power Modes
Which technique involves reducing the processor's clock frequency to save power?
Which technique involves reducing the processor's clock frequency to save power?
easy📝 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Identify the technique that changes clock frequency
DVFS adjusts voltage and frequency to save power.Step 2: Compare with other options
Instruction pipelining, cache prefetching, and branch prediction improve speed but don't reduce clock frequency.Final Answer:
Dynamic voltage and frequency scaling (DVFS) -> Option AQuick Check:
Clock frequency reduction = DVFS [OK]
Quick Trick: DVFS changes voltage and frequency to save power [OK]
Common Mistakes:
- Confusing pipelining with frequency scaling
- Thinking cache prefetching saves power by lowering frequency
- Assuming branch prediction affects clock speed
