这里介绍一个能同时完成加法和进位传送的高速加法器线路。一般的加法技术中,通常都是把进位与加法操作分开来处理。甚至在所谓“同时进位”的线路中,进位传送时间也达到了两倍到十倍的正常加法时间。此处介绍的新方法是把加法过程分为“加进位”或“加无进位”的操作。加法指令脉冲可在这两条线中的一条上传送,但不能同时都有。当加法过程结束了,进位传送也就结束。在连续的加法操作之间不要求有 Here is a high-speed adder circuit that can perform addition and carry-on simultaneously. In general addition techniques, the carry and add operations are usually handled separately. Even in the so-called “Simultaneous Carry” line, carry transfer time has reached twice to ten times the normal addition time. The new method introduced here is to divide the addition process into “plus bit” or “plus no carry” operation. The addition instruction pulse can be transmitted on one of these two lines, but not both at the same time. When the addition process is over, the carry transfer also ends. There is no requirement between consecutive addition operations
