WebJun 30, 2024 · Outside of a CPU, clocks tend to be point-of-use so little power is saved by disabling a clock. Instead, power is saved by disabling data flow using chip selects and gating the data itself or by slowing the data rate. Slowing the clock rate also saves power and cuts down on heat, which saves power used for cooling. WebClock is the periodic synchronisation signal in synchronous digital systems and accounts for about 40% of the total power dissipation of the entire system. For power reduction, …
