因为二进制加法的进位只可能是1或0，所以可以将32位加法器分为8块（最低一块由4位先行进位加法器直接构成，其余加法结构都采用先行进位加法器结构）分别进行加法计算，除最低位以外的其他7块加法器结构各复制两份，进位输入分别预定为1和0。于是，8块加法器可以同时进行各自的加法运算，然后根据各自相邻低位加法运算结果产生的进位输出，选择正确的加法结果输出。-Because binary adder carry only be 1 or 0, so it can be 32-bit adder is divided into eight (minimum one by the four carry-lookahead adder directly constitute the remaining adder structures using carry-lookahead adder structure), respectively Addition calculation, in addition to other than the lowest seven two copies of each adder structure, carry input is scheduled for 1 and 0, respectively. Thus, the adder 8 can be performed simultaneously the respective adder, and then the respective adjacent low addition result generated carry bit output, select the correct output of the addition result.
