Clock gate efficiency
WebFeb 9, 2024 · You can either use a latch or flip-flop to ensure the clock gating signal only transitions on the inactive edge of the clock. For latch: always_latch if (~clk) enable_latch <= enable_in; assign g_clk = clk & enable_latch; For flip-flop: always_ff @ (negedge clk) enable_flop <= enable_in; assign g_clk = clk & enable_flop; 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…
