[assembly language] WXZ DL : 0: 加法器是产生数的和的装置。加数和被加数为输入，和数与进位为输出的装置为半加器。若加数、被加数与低位的进位数为输入，而和数与进位为输出则为全加器。常用作计算机算术逻辑部件，执行逻辑操作、移位与指令调用。在电子学中，加法器是一种数位电路，其可进行数字的加法计算。在现代的电脑中，加法器存在于算术逻辑单元（ALU）之中。加法器可以用来表示各种数值，如：BCD、加三码，主要的加法器是以二进制作运算。由于负数可用二的补数来表示，所以加减器也就不那么必要。-The adder is generated the number of and apparatus. Addend and augend input sum and carry bits of the output means is a half adder. If the addend, augend and the low decimal input, and the sum and carry output is a full adder. Commonly used for computer arithmetic logic unit, perform logical operations, shift instruction calls. In electronics, the adder is a digital circuit, which may be a digital sum. In modern computers, the adder is present being in the arithmetic logic unit (ALU). Adder can be used to represent various values , such as: BCD, plus three yards main adder based on binary for computing. Negative two s complement available to represent the addition and subtraction is not so necessary
