A combinational circuit that has three inputs that are an augend, D, an addend, E, and carry digit transferred from another digit place, F, and two outputs that are a '. 三个输入端是:被加数d、加数e以及从另一个数位传来的进位数f;两个输出端是:无进位和数t及新的进位数r。
In parallel addition, a carry which is produced in one digit place as a result of addition for that digit place and which is propagated to the next high-order digit place. 在并行加法中,一个数字位因在该数位上做加法而产生的进位,该进位并被送至下一个高位数位。
