Design of High Speed and Low Area Confined Multiplier on FPGA

In this Advanced world, Technology is playing the major role. Most importantly development in Electronics field has a large impact on the improved life style. Among the advanced applications, DSP ranks first in place. Multipliers are the most basic elements that are widely used in the Digital Signal Processing (DSP) applications. Therefore, the design of the multiplier is the main factor for the performance of the device. Using RTL simulation and a Field Programmable Gate Array (FPGA), we compare the performance of a serial multiplier with an advanced multiplier. Many single bit adders are removed and replaced with multiplexers in this project. So that the less often used FPGAs are fully used by occupying fewer divisions and slices. The use of multiplier architecture results in significant reductions in FPGA resources, latency, area, and power. These multiplication approaches are created utilizing RTL simulation in Xilinx ISE simulator and synthesis in Xilinx ISE 14.7. Finally, the Spartan 3E FPGA is used to implement the design.

An Efficient Reverse Converter for the Four Non Coprime Moduli Set {2n,2n-1,2n-2,2n-3}

In this paper, residue to binary conversion is presented for the four moduli setsharing a common factor. A new and efficient converter for the moduli set using multipliers, carry saves and modular adders is proposed based on a cyclic jump approach. A theoretical hardware implementation and comparison with a state-of- the- art scheme showed that the proposed scheme performed better. The 4- moduli set selected provides a larger dynamic range which is needed for Digital Signal Processing (DSP) applications [7].

Design and Analysis of Multiplier Using High Speed Adders

In all digital signal processing (DSP) applications like FFT, digital filters the main problem faced by processor is its propagation delay. Every high speed signal processing is depends on multiplier circuits. Multiplier performance is directly influenced by the adder design. In this paper, we design low power and high speed carry look ahead (CLA) adder for multiplier circuit by using multi value logic (MVL) based on quaternary signed digits (QSD). The ability of multi value logic (MVL) circuits to achieve more information density and high operating speed when compared to that of existing binary circuits is highly impressive. MVL circuits have attracted important attention for the design of digital systems. Based on quaternary signed digits, the carry look ahead adder is designed, implemented in multiplier circuit and simulated by using cadence virtuoso design suite by 180nF technology.

FPGA Implementation of Proficient 16-Tap FIR Filter Design Using Decision Tree Algorithm

Lately, channel is one of the key components in signal handling applications. Among different channels, Finite Impulse Response (FIR) channel is broadly utilized in Digital Signal Processing (DSP) applications for shifting/denoising. For enormous scope coordination (VLSI) execution of fixed-coefficient FIR channels, huge asset used customary multipliers that can be acknowledged by a solitary steady multiplication (SCM) and numerous consistent augmentations (MCM) square utilizing movement and include/take away tasks. For a proficient execution, a variable size apportioning approach is proposed in direct structure channel structure that devours less zone and 11% of decrease in basic way delay, 40% decrease of all out force utilization, 15% decrease of zone delay product(ADP), 52% decrease of vitality delay product(EDP), and 42% decrease of intensity territory product(PAP), on a normal, over the cutting edge techniques. In this paper, a state choice tree calculation is proposed to decrease unpredictability in channel tap cells of variable size apportioning approach. The proposed plot creates a choice tree to perform move and expansion/deduction and aggregation dependent on the consolidated SCM/MCM approach. This plan diminishes the quantity of postpone registers required for tab cells. The proposed snake design will be actualized in Xilinx Zed, Spartan and Virtex devices and Area, power and speed investigation will be performed.
