0x02 D 触发器(D Flip-Flop) 通过将 RS 触发器的输入 和 绑定为互补值,可以构建一个只有一个输入的 触发器。 要设置为 '1',只需在输入上放置 '1';要设置为 '0',只需在输入上放置 '0'。 0x03 JK Flip-Flop(JK 触发器) JK 触发器是一种在 RS 触发器中不被允许的输入 被允许的触发器。 当两...
flip-flop是触发器,只有在被时钟触发时才采样当前的输入,产生输出。如果使用门电路来搭建latch和ff,则latch消耗的门资源比ff要少。但是你用的如果是 fpga,那么内部一般带DFF单元,反而用触发器更好。 22、latch与register的区别, 为什么现在多用register.行为级描述中latch如何产生的行为级描述中latch一般是由于if或ca...

There are two types of D Flip-Flops being implemented: Rising-Edge D Flip Flop and Falling-Edge D Flip Flop. D flip flop is an edge-triggered memory device that transfers a signal's value on its D input to its Q output when an active edge transition occurs on its clock input. Then,...
