Design of 9-Tap Fir Filter Using High Speed Low Power Vedic Reversible Multiplier

The area, power dissipation, speed, cost etc are the real challenges of the VLSI outline. In this paper, we have designed a 9-Tap FIR filter using Vedic reversible multiplier. The design is explicitly focused on achieving more speed and less power dissipation. The multipliers utilize the most important part of the computation in any arithmetic operation of CPU. Here we designed a multiplier concentrated on the speed and the power dissipation. The speed of the multiplier is increased by designing it with a concept called Vedic mathematics. Vedic mathematics consists of 16 sutras (algorithms), out of which Urdhva Tiryakbhyam (UT) sutras is used for multiplication. Hand in hand with speed, power reduction is also important. We have used a technique called reversible logic with which Vedic multipliers can be implemented. The combination of reversible logic and Vedic multiplier turns into a perfect system where both low power and speed can be achieved. The proposed digital 9-Tap FIR filter is coded using verilog language and the performance of the design is evaluated and synthesized using Xilinx 13.1 synthesis tool.
