Now, what happens if CLK_ENABLE is high? the output of AND gate doesn't go high immediately because latch is opaque during high cycle of clock. Only when clock is low, CLK_ENABLE is pass through the latch the AND gate. When clock goes back to high cycle, since CLK_ENABLE is already asserted, …

WebFeb 13, 2012 · When the data falls in the setup-hold window of the clk, the output of FF1 becomes metastable. This situation gives rise to two sub-cases (i) first edge of the clk_gated coincides with second clk edge. (ii) first edge of the clk_gated coincides with 3rd, 4th or 5th clk edge. In sub-case 1, FF2 captures the metastable data at second clk … WebThis rising-edge detector can be designed by double registering (say clk_reg1 and clk_reg2) the gated-clock signals using the faster clock and then forming a logic to detect the change from LOW to HIGH (NOT(clk_reg2) AND clk_reg1) as shown in • Figure 74.

WebExpert Answer. Background A Flip-Flop is a gated latch with a clock input. The flip-flop output changes when its CLOCK input (CLK) detects an edge. This sequential circuit element is edge-sensitive and not level sensitive, as the latch). ការ។ MO M Figure 5.5.4. WebIn simplest form a clock gating can be achieved by using an AND gate as shown in picture below. Figure 1: AND gate-based clock gating. The clock enable signal, generated by a combinatorial logic, controls when to provide the clock to the downstream logic (FF in the above figure). When enable is 1, the clock will be provided to FF and when ...

WebOct 26, 2024 · Clock gating is a way reducing dynamic Power dissipation by temporary turning-off clock of the Flops on certain parts of the logic or by turning-off enable on gated Flops. In other words, Flops are turned-on only if there is valid information to be stored or transferred. The accuracy with which these clocks are Turned-off is captured by clock ...
