本文旨在探讨一种基于Flip-Flop(触发器)和Logic-Gate(逻辑门)的1位加法器设计,该设计不仅实现了基本的加法功能,还巧妙地融入了时钟信号控制,使得加法操作能够在特定的时钟周期内完成。通过深入分析输入信号(carryin和current-stage)、输出信号(next-stage和carryout)以及它们之间的逻辑关系,本文将详细阐述这一设计的实现...

and can be used to store state information. The state can be changed by applying one or more control inputs and will have one or two outputs. It is the basic storage element in the digital circuit diagram. The logic circuit designer will have SR, D, JK, and T flip-flops for ...
Starting from the excitation table for the JK Flip-flop, this paper introduces the logic design of synchronous sequential circuit and asynchronous sequential circuit based on single-edge-triggered JK flip-flop, and proposes the complete state equation. Besides, it discusses the logic design of asynch...
