Web专利名称：Clock gating circuitry for reducing dynamic power 发明人：カイ、ヤンフェイwk.baidu.comリ、ジ,ダイ、キアン申请号：J P 20155314 19 申请日：20120919 公开号：JP6039081B2 公开日：20161207 WebClock gating is a methodology of turning off the clock for a particular block when it is not needed and is used by most SoC designs today as an effective technique to save dynamic power. In SoC designs clock gating may be done at two levels: • Clock RTL gating is designed into the SoC architecture and coded as part of the RTL functionality. In computer architecture, clock gating is a popular power management technique used in many synchronous circuits for reducing dynamic power dissipation, by removing the clock signal when the circuit is not in use or ignores clock signal. Clock gating saves power by pruning the clock tree, at the cost of adding more logic to a circuit. Pruning the clock disables portions of the circuitry so that the flip-flops in them do not have to switch states. Switching states consumes power. When not b… sup konro
