For the partial products generation, the novel method of Booth encoding combined with partial products generating is put up, which can directly map the multiplicand and multiplicator to partition products without generating the BOOTH encoding results.

• 对于BOOTH编码和部分积产生，提出了直接建立被乘数与部分积的多路选择映射关系的BOOTH编码和部分积联合产生方法；
