What is Clock gating?

Clock gating in the explanations

• Typical uses include clock gating, which ANDs the clock with an enable so the clock passes only when needed, and bit masking (x AND 0x0F keeps the lower four bits).

  When is the output of a 2-input AND gate 1?

• Clock gating stops the clock to blocks that do not need to operate, eliminating needless switching of flip-flops and clock wiring and reducing dynamic power.
