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
