💭 写在前面:本章将理解 RS/D 锁存器的概念,了解 RS/D/JK 触发器的概念,使用 Verilog 实现各种锁存器 (Latch) 和翻转器 (Flip-Flop),并通过 FPGA 验证用 Verilog 的实现。 📜 本章目录: Ⅰ. 前置知识回顾 0x00 锁存器(Latch) 0x01 RS 触发器(RS Flip-Flop) ...
触发器:flipflop 锁存器:latch 寄存器:register 锁存器是电平触发的存储单元,数据存储的动作取决于输入时钟(或者使能)信号的电平值,仅当锁存器处于使能状态时输出才会随着数据输入发生变化。 触发器是边沿敏感的存储单元,数据存储的动作由某一信号的上升或者下降沿进行同步的。
create a 4-to-1 multiplexer (not provided) that chooses what to output depending on sel[1:0]: The value at the input d, after the first, after the second, or after the third D flip-flop. (Essentially, sel selects how many cycles to delay the input, from zero to three clock cycle...
