Abstract:
This study represents designing and implementation of a low power and high speed 16 order FIR filter. To optimize filter area, delay and power, different multiplication techniques such as Vedic multiplier, add and shift method and Wallace tree (WT) multiplier are used for the multiplication of filter coefficient with filter input. Various adders such as ripple carry adder, Kogge Stone adder, Brent Kung adder, Ladner Fischer adder and Han Carlson adder are analyzed for optimum performance study for further use in various multiplication techniques along with barrel shifter. Secondly optimization of filter area and delay is done by using add and shift method for multiplication, although it increases power dissipation of the filter. To reduce the complexity of filter, coefficients are represented in canonical signed digit representation as it is more efficient than traditional binary representation. The finite impulse-response (FIR) filter is designed in MATLAB using equiripple method and the same filter is synthesized on Xilinx Spartan 3E XC3S500E target field-programmable gate array device using Very High Speed Integrated Circuit Hardware Description Language (VHDL) subsequently the total on-chip power is calculated in Vivado2014.4. The comparison of simulation results of all the filters show that FIR filter with WT multiplier is the best optimized filter.

Base Paper Abstract:
One of the primary purposes of a digital signal processing system is multiplication. The multiplier’s performance affects the DSP system’s overall performance. Therefore, it is crucial to create an effective and quick multiplier implementation design. Vedic mathematics can be used to simplify complex computations so that they are easier to perform verbally. Urdhva Triyambakam is the multiplication algorithm used in Vedic math. In this paper, we employing Brent Kung adder to enhance the Vedic multiplier’s performance. The Urdhva Tiryagbhyam sutra is being used in place of other multiplication strategies since it applies to all instances of algorithms for N x N bit numbers and produces the least amount of latency. Four 4-bit vedic multipliers, two 8-bit Brent Kung adders, one 4-bit Brent Kung adder, and an OR gate are used to create an 8-bit vedic multiplier. A 4-bit vedic multiplier is created similarly by combining four 2-bit vedic multipliers, two 4-bit Brent Kung Adders, one 2-bit Brent Kung Adder, and one OR gate. These four-bit vedic multipliers are then combined to form an eight-bit vedic multiplier. After that, Xilinx Vivado Software is used to simulate and synthesis the 8 x 8 Vedic Multiplier, which was coded in Verilog HDL. The proposed Vedic Multiplier is outperformed in terms of speed when compared to related works.

Vedic mathematics is a unique technique of carrying out mathematical computations and it has its roots in the ancient Indian Mathematics. This paper presents the divider architecture using one of the Vedic mathematics techniques called as Paravartya-Yojayet, which means to transpose and apply. This paper proposes a fast, low power and cost effective architecture of a divider using the ancient Indian Vedic division algorithm. The merits of the proposed architecture are proved by comparing the gate count, power consumption and delay against the conventional divider architectures. The proposed architecture of this paper analysis the logic size, area and power consumption using Xilinx 14.2.
