【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.
[Abstract]:The Han-Carlson structure is a parallel prefix adder between the Kogge-Stone structure and the Brent-Kung structure, and combines the advantages of the two structures. Based on the parallel prefix adder of Han-Carlson structure, the characteristics of the parallel prefix adder are studied and analyzed, and the tradeoff between delay and area is selected. An optimization scheme is proposed to reduce power consumption by sacrificing partial delay and reducing usage area. The comparison with the unoptimized Han-Carlson adder and the hybrid adder shows that the proposed scheme can reduce the area and power consumption successfully.
