Every processor multiplier acts as the basic building block which decides the performance of processor. Time and again research is going on to design high-performance, low-latency BCD multiplier architectures. This paper proposes a new approach to BCD multiplication using vinculum number system. The key feature of the proposed architecture uses entirely a new one digit ROM based BCD multiplier that uses vinculum numbers as operands. Using this one digit BCD multiplier, an N digit BCD multiplier is built by using the vedic vertical cross wire method (Urdhav Triyagbhyam). We have also used our proposed multi operand VBCD Adder (Vinculum BCD Adder) [my paper 26] to add the partial products. In this paper, we show that this approach is a promising alternative to conventional BCD multiplication or other decimal multiplication methods that use alternative decimal representations like 5211, 4221, Xs3 etc.展开更多

The FIR filter is mostly employed in filtering applications to enhance the quality of the signal. In any processor, the performance of the system is based on the speed of the multiplier unit involved in its operation. Since multiplier forms the indispensable building blocks of the FIR filter system. Its performance has contributed in determining the execution of the FIR filter system. Also, due to the tremendous development in the technology, many approaches such as an array, Vedic methods are made to speed up the multiplier computations. The problem in speed-up operation and resource utilization of hardware with all the conventional methods due to the critical path found in partial products has to be optimized using proposed method. This paper presents the implementation and execution of a FIR Filter design using Anurupye multiplier. Here the FIR filter is examined by using various multiplier algorithms such as Anurupye, Urdhava Tiryagbhyam, and array multipliers. The FIR filter is simulated for analyzing delay;area and power are meted out and lessened by utilizing proposed Anurupye multiplier. The FIR filter design utilizing proposed multiplier offers delay around 18.99 and only 4% of LUT slice utilization compared to existing methods. This architecture is coded in VHDL, simulated using the ModelSim and synthesized with Xilinx.展开更多
