对于更多bit的加法器比如16bit的,我们可以将上述建立的4bit加法器作为一个基本模块,在其上在构建一级4次例化调用4bit加法器的16bit加法器。 3.加法器时延控制(资源换时间) 对于这种行波(进位)加法器(ripple carry adder),随着bit位数的增加会增加计算延时,不利于低时延的应用,对延时控制的核心思路就是并行化处理...

Now that you know how to build a full adder, make 3 instances of it to create a 3-bit binary ripple-carry adder. The adder adds two 3-bit numbers and a carry-in to produce a 3-bit sum and carry out. To encourage you to actually instantiate full adders,also output the carry-out ...
