针对当前乘法器设计难以平衡版图面积和传输延时的问题,本文采用Radix-4 Booth算法,设计了一种新型的16位有符号定点乘法器。在部分积生成过程中:首先改进对乘数的取补码电路,然后优化基数为4的改进Booth编码器和解码器,此结构采用较少的逻辑门资源,并且易对...
本乘法器采用基4booth编码,输入为两个128位有符号数,输出为256位有符号数。 基4的booth编码将两个128位有符号数计算成64个部分积。 64个部分积经过一层4-2压缩器得到32个部分积……在经过几层4-2压缩器,最终得到两个部分积, 两个部分积进过一个超前进位加法器(cla)得到最终结果。 结构框图如下: ...

With this precept, a family of radix-8 Booth encoded modulo 2 n 1 multipliers, with delay adaptable to the RNS multiplier delay, is proposed. The modulo 2 n 1 multiplier delay is made scalable by controlling the word-length of the ripple carry adder, k employed for radix-8 hard multiple...
In Section 3, we show how to very slightly adapt a conventional multiplier so that it can also handle RN-codings. 2 Improvement of the Multiplication Algorithm Proposed in [2] Our first multiplication algorithm, published in [2], consists in computing XY = X + Y + +X − Y − ...
