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.
