Low Power Dissipation Binary to BCD Converter for Multi-Operand B/D Adder

The main objective to design this paper to increasing importance of commercial application , economic and Internet-based applications the decimal adder provide useful statistic in formative each adder's performance and scalability. There is a new interest in providing hardware support to handle decimal data. In this paper, a new architecture binary to BCD converter for multi-operand addition implement of binary coded decimal (BCD) operands, which is the core of high speed multi-operand adders. the proposed Simulation results show that the add-3 digit BCD adder achieves an improvement of 70 % in delay and area and it consume very less power. The 2,4,8,16-digit BCD look-ahead adder shown to achieve at least 90 % faster than the accessible ripple carry one. The coding will be written in VHDL and verified in I-Sim. After the coding the synthesis of the code was performed using Xilinx-ISE. Synthesis tool ISE 14.7.
