全加器是由两个加数Xi和Yi以及低位来的进位Ci-1作为输入，产生向高位的进位Ci以及本位利Si的逻辑电路。 (65) 和 (66) 分别是进位和本位和的正确逻辑表达式。全加器亦可通过半加器来实现，此时Si= (67) 。若某计算机采用8位带符号补码表示整数，则可由8个全加器(i =1，2，……8，i=8为最高位，即符号位)串接构成8位加法器，CO=0。该加法器有一个状态寄存器，记录运算结果的状态。其中，N和V分别表示符号位与溢出标志位，则其逻辑表达式分别为 (68) 和 (69) 。

A．XiYiCi-1+XiYiCi-1+XiYiCi-1+XIYiCi-1

B．Ci-1(XiYi+XiYi)+Ci-1(XiYi+XiYi)

C．Ci(XiYi+XiYi)+Ci(XiYi+XiYi)

D．Ci(Xi+Yi+Ci-1)+XiYiCi-1
