实现17位加法，利用一个16位超前进位加法器和一个一位全加器构成的一个有进位输入和进位输出的17加法器，并且16位加法器利用的使四位超前进位加法器构成。它在booth乘法器设计中经常用到。可以使初学者对模块的调用了解更加透彻。-Adder 17 to achieve the use of a 16-bit CLA, and a one-bit full adder composed of a binary input and binary output of the adder 17, and 16-bit adder to make use of four CLA pose. Multiplier in the booth design frequently used. Modules will enable beginners to a more thorough understanding of the call.
