Q62 / 100
What is "clock gating," and why is it used in low-power digital design?
Correct! Well done.
Incorrect.
The correct answer is A) A power-saving technique where the clock signal to a portion of a circuit is disabled when that portion is not needed, preventing unnecessary switching activity and reducing dynamic power consumption
A
Correct Answer
A power-saving technique where the clock signal to a portion of a circuit is disabled when that portion is not needed, preventing unnecessary switching activity and reducing dynamic power consumption
Explanation
Since switching the clock input of unused flip-flops/registers consumes dynamic power even if their data doesn't change, gating off the clock to idle blocks reduces unnecessary power usage — a common technique in modern low-power chip design.
