昨天受到HDLBits(Module cseladd - HDLBits (01xz.net)一道题启发,用全加器搭建了16位加法器,再利用2个16位加法器组成32位加法器。后来了解到这种方法搭建的是行波进位加法器(Ripple Carry Adder, RCA),加法器的下一位要依赖于低位进位,影响到整体加法器的运行速度。而HDLBits提供了改进型加法器——进位选择加法...

与之前的Module_Hierarchy_add1与2有一定区别,使用了三个add16,但是计算速度会快一些。但是前面的Module_Hierarchy_add1与2结构计算速度慢,使用的器件会更少一些。 用了两个二级加法器计算了进位输入为0与1所对应的结果,该计算过程与一级加法器同时进行,当一级加法器计算结束时,二级加法器会根据一级加法器的进位...

SquareRootCarrySelectAdder64是一个64位的平方根进位选择加法器,用于实现二进制加法。它由四个部分组成:平方根进位选择逻辑、进位输出逻辑、加法逻辑和进位输入逻辑。 1. 平方根进位选择逻辑:该部分负责根据输入值计算平方根,并将结果存储在相应的位置。当输入值为负数时,将产生一个进位信号。 2. 进位输出逻辑:该...
