本实验要完成的任务是设计一个四位二进制全加器。具体的实验过程就是利用实验系统上的拨动开关模块的SW17~SW14作为一个加数X输入，SW13~SW10作为另一个加数Y输入，用LED模块的LEDG0~LEDG4来作为结果S输出，LED亮表示输出‘1’，LED灭表示输出‘0’。-To complete the task of the experiment is to design a four bit binary full adder. The specific experimental process is the use of the toggle switch on the module in the experimental system input as a summand X SW17 ~ SW14, SW13 ~ SW10 as another addend Y input, as a result of S output LED module LEDG0 ~ LEDG4, LED Liang said output ' 1 ' LED off means output ' 0' .
