摘要：

本次实验的功能是进行两个4位数的加法运算，并进行结果输出。在本次实验中，我们用到data_bus作为总线进行传输，reg_74373作为寄存器进行数据的存储，alu_74181进行加法运算。romc作为译码器进行初始状态的设定。通过这个加法器的设计，能够对硬件结构设计有了更好的了解，同时也加深了对计算机组成原理课程的理解。

硬件结构设计原理：

1.把模块romc改为九位输出oen,we1,we2,gwe1,oen_n1,gwe2, oen_n2,gwe3,oen_n3；

2.把模块reg_74244改为四位输入Din(3 0)和四位输出Qout(3 0)；

3.把模块data_bus改为四位输入data_in1(3 0),Data_in2(3 0),四位输出data_out1(3 0),data_out2(3 0),data_out3(3 0);

4.把模块reg_74373改为四位输入Din(3 0)和四位输出Qout(3 0)；

5.把模块alu_74181改为四位输入A(3 0),B(3 0),S(3 0),和四位输出F(3 0)

6.由romc向reg_74244中分别输入两个四位二进制的数，通过九位romc微程序控制器，在进入data_bus后，两个数分别被写入两个reg_74373中，再进入alu_74181进行加法运算，将运算结果输入data_bus，再由另外一个reg_74373读出。
