四位二进制加法器课程设计

一、题目名称

四位二进制加法器

二.技术要求

1.四位二进制加数与被加数输入

2.二位数码管显示

三、前言和摘要

四位二进制加法器的设计包括：1、四位二进制加数和被加数的输入，

2、两个数的相加运算和和的输出，3、将两个数的和通过译码器显示在数

码管上。二进制数的输入可以通过数据开关实现，用加法器可以进行二进

制数的加法运算。两个四位二进制数相加后的和在十进制数的0~30内，

其中产生的进位和对十进制数十位的判断和显示是重点和难点，这需要通

过译码器来实现。对数据译码后即可用合适的数码管与译码器相连，显示

数据。

四、总体设计方案的论证和元件选择

1、加法器的选择

在数字系统中，经常需要进
