图1是Xilinx D Flip-Flop的示意图。D端是我们熟悉的数据输入端,Q端是数据输出端,C端则是时钟输入端,CLR是复位端(上一篇专栏文章提到的)。CE端便是这次我们要了解的Clock Enable。 图1 - DFF with Clock Enable and Asynchronous Clear 那么CE端有什么用呢,Xilinx文档里有这样的描述 When clock enable (CE) ...
Clock gated flip-flop
In the ALM block diagram shown above, in the D flip flop, I can see the D input, the Clk input, CLR input and the Q output but i cannot see the ENA(enable) pin? How is the Enable pin(ENA) on the D flip flop seen in my RTL viewer getting implemented with the actu...
FDRE: Flip-Flop with Asynchronous Reset and Clock Enable 的缩写。带有异步复位和时钟使能的触发器(Flip-Flop)。FDRE 经常用于存储和传递数据,在数字逻辑电路中起着重要作用。 CARRY4:CARRY4 是用于实现数字电路中的加法逻辑的元件。它能够对四位二进制数的加法进行处理,同时考虑进位(carry)情况。
RTL clock gating works by identifying groups of flip-flops which share a common enable control signal. Traditional methodologies use this enable term to control the select on a multiplexer connected to the D port of the flip-flop or to control the clock enable pin on a flip-flop with clock...

Hex D Flip-Flop with Common Clock and Reset NLSF1174 This device consists of six D flip-flops with common Clock and Reset inputs. Each flip-flop is loaded with a low-to-high transition of the Clock input. Reset is asynchronous and active low. All inputs/outputs are standard CMOS ...
is clock gated to save power. The flip-flop110operates in response to a clock signal CLK to sample a data input (D), hold the data input for a period of time and generate a data output (Q). The flip-flop110includes a clock gating and buffer circuit140configured to buffer the clock ...
