文档介绍：-1- 前言本次课程设计介绍了一种基于数字电子技术的八位二进制加法器, 实现了如下功能:1、八位二进制加数与被加数输入 2、三位数码管显示 3、三位十进制加数与被加数的输入该电路系统主要分为八位二进制加法器和三位十进制加法器两个系统: 八位二进制加法器系统由二进制输入电路、二进制加法运算电路、二进制码到十进制 8421BC D 码的转换电路和三位数码管显示输出4 个模块组成; 三位十进制加法器系统由十进制的输入电路、三位十进制 8421BCD 码加法运算电路、四位数码管显示输出 3 个模块组成。设计过程: 首先由本小组三名同学:夏程鉴,邢晓理,王维在互联网以及图书馆查阅了相关资料与文献, 并参考了清华大学出版社 06 年版《数字电子技术基础》等参考教材,进行了资料整理以及设计构思。随后三名组员分工设计,由邢晓理同学设计输入系统电路,王维同学设计加法系统电路,夏程鉴同学设计二进制_ 十进制 BCD 码转换系统电路和输出系统。最后将电路模块整合为一个整体电路系统,并应用 Multisim 软件进行了设计电路图的绘制和仿真检验。-2- 目录前言····················································1 摘要····················································3 关键词····················································3 设计要求··················································3 一、设计方案简介 1、方案一················································4 2、方案二················································5 3、方案三················································6 二、单元电路设计与分析 1 、八位二进制加数与被加数输入( 邢晓理)····················7 2 、八位二进制数的加法运算( 王维)······················
