When Clk = high (1) T1 is ON and T2 is OFF, so output (Q) directly follows the input (D). When Clk = low (0) T1 is OFF and T2 is ON, now new data entering into the latch is stopped and we get only previously-stored data at the output.

WebThe design ensures that no clock activates until all others are inactive for at least a few cycles, and that activation occurs while the clock is low. The design applies a synthesis_keep directive to the AND gates on the right side, which ensures there are no simultaneous toggles on the input of the clk_out OR gate.

WebThere is one main clock that supplies the design. This main clock (from a PLL) is split into two clocks - one that´s always running and one with a clock gate. This is to turn off some parts of the design to save power. So, it roughly looks like this: cpu_clk = main_pll_clk_out; gated_cpu_clk = main_pll_clk_out & enable; Web[ASPEED_CLK_GATE_REF0CLK] = { 6, - 1, "ref0clk-gate" , "clkin", CLK_IS_CRITICAL }, [ASPEED_CLK_GATE_USBPORT2CLK] = { 7, 3, "usb-port2-gate" , NULL , 0 }, /* USB2.0 Host port 2 */ /* Reserved 8 */ [ASPEED_CLK_GATE_USBUHCICLK] = { 9, 15, "usb-uhci-gate" , NULL , 0 }, /* USB1.1 (requires port 2 enabled) */
