Which component in an ARM processor is directly controlled by clock gating?

easy📝 Conceptual Q2 of 15
ARM Architecture - Power Modes
Which component in an ARM processor is directly controlled by clock gating?
AThe power supply voltage
BThe clock signal to functional blocks
CThe instruction set architecture
DThe cache memory size
Step-by-Step Solution
Solution:

  1. Step 1: Identify what clock gating controls

    Clock gating controls the clock signal that drives functional blocks inside the processor.

  2. Step 2: Exclude unrelated components

    Power supply voltage, instruction set, and cache size are not directly controlled by clock gating.

  3. Final Answer:

    The clock signal to functional blocks -> Option B

  4. Quick Check:

    Clock gating controls clock signals [OK]
Quick Trick: Clock gating controls clock signals, not voltage or architecture [OK]
Common Mistakes:
  • Confusing clock gating with power voltage control
  • Thinking it changes instruction sets
  • Assuming it modifies cache size
