摘要

本文介绍了在Xilinx FPGA上实现十进制乘法算法的几种方法。提出了多种基本的1乘1数乘法算法,并给出了FPGA实现。随后研究了N × 1位和N × M位乘法。时序和组合实现的时间和面积结果与先前发表的工作相比显示出更好的数字。与二进制完全优化乘法器的比较强调了所提出的设计技术的兴趣。

FPGA Implementations of BCD Multipliers
This paper presents a number of approaches to implement decimal multiplication algorithms on Xilinx FPGA’s. A variety of algorithms for basic one by one digit multiplication are proposed and FPGA implementations are presented. Later on N by one digit and N by M digit multiplications are studied. Time and area results for sequential and combinational implementations show better figures compared with previous published work. Comparisons against binary fully-optimized multipliers emphasize the interest of the proposed design techniques.
