摘要
Han-Carlson结构是介于Kogge-Stone结构和Brent-Kung结构之间的一种并行前缀加法器,并且结合了两种结构的优势.基于Han-Carlson结构并行前缀加法器,对其结构特点进行研究分析,在延时和面积上进行折中选择,提出了一种优化方案,牺牲部分延时,减少使用面积以降低功耗.将其与未优化的Han-Carlson加法器以及混合加法器进行对比后表明,该优化方案成功减少了使用面积,降低了功耗.
Han-Carlson parallel-prefix adder is a combination of Kogge-Stone adder and Brent-Kung adder＇s advantages. This paper proposes a method of optimization based on Han-Carlson parallel-prefix topology. Sacrificing part of the delay and reducing the use of area to reduce power consumption. Comparing with unoptimized Han- Carlson parallel-prefix adder and mixed adders based on Han-Carlson parallel-prefix adder, the proposed method is succeed to reduce the using area and power.
