WebClock gating can be used to reduce dynamic power consumption. When an application is idle, its clock can be gated temporarily and ungated based on wake-up events. This is done using user logic to enable or disable the programmable clock routing. WebJun 30, 2024 · I am comparing Clock Gating (ECG) and Data enable methods in term of power reduction. Both can save power. But which one is better? I tried these 2 methods in a small design ( a d flipflop ) to a larger one (8-bit data register) and measured their power dissipation. The results always show that Data enable consumes less power than Clock …
