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.

WebMar 31, 2024 · The design has two clock sources, both from hardware external to the FPGA. These two clocks are synchronous, from a common oscillator, with gated_clk delayed from sys_clk by about 1.3ns. gated_clk is used to latch in data, and this is later timed with sys_clk. See the attached block diagram. WebOct 13, 2024 · Often, the clock signal drives a large capacitive load, making these signals a major source of dynamic power dissipation. Clock gating reduces power dissipation for the following reasons: • Power is not dissipated during the idle period when the register is shut-off by the gating function. • Power is saved in the gated-clock circuitry.
