论文摘要
在随身携带的加法器中，携带传播是关键延迟。对于他们使用的1位添加剂，最有效的方案是生成两个中级携带：c $ _ {out0} $（$ c_ {in} $ = 0）和$ c_ {out1} $（$ c_ {$ c_ {in} $ = 1）。然后将它们复用以根据$ C_ {in} $产生正确的输出。对于任何radix，随身携带的输出始终具有逻辑值0或1。我们显示，用于输入的0和$ v_ {dd} $级别用于输入，输出代替0和$ v_ {dd} $/3在第四纪完整添加器中，大大减少了随身携带的传播。我们将这样的第四纪完整加法器与二进制完整加法器进行比较，以实现N位数携带的繁殖加法器。
In Carry Propagate Adders, carry propagation is the critical delay. For the 1-digit adders that they use, the most efficient scheme is to generate two intermediate carries: C$_{out0}$ ($C_{in}$=0) and $C_{out1}$($C_{in}$=1). Then multiplex them to produce the correct output according to $C_{in}$. For any radix, the carry output has always a logical value 0 or 1. We show that using 0 and $V_{dd}$ levels for input and output carries instead of 0 and $V_{dd}$/3 in quaternary full adders significantly reduce the carry propagation. We compare such a quaternary full adder with binary full adders to implement N-digit carry propagate adders.
