New Approach: Design of Compact Baugh-Wooley Multiplier Using Reversible Logic | Chapter 4 | New Insights into Physical Science Vol. 12

 Developing digital circuits in today's digital age is constrained by research into various nano devices. The concept of a compact Baugh-Wooley multiplier using reversible logic is discussed in this paper. Despite the fact that there have been several studies on how to construct a reversible multiplier, this is the first in the literature to use the Baugh-Wooley algorithm with reversible logic. A new 5 5 reversible multiplier cell is proposed in this paper, which will be useful in the design of Baugh-Wooley multipliers. The proposed single multiplier cell will add a one-to-one product with the total and carry from the previous cell. This reversible multiplier cell is useful for ensuring array multiplier regularity. The proposed reversible multiplier cell's Toffoli gate synthesis is also given. It is understood that the proposed architecture has fewer gates, constant inputs, and garbage outputs values than current approaches. The circuit can be modified to create n n reversible Baugh-Wooley multipliers.

Design of 2048-point Split-Radix Fast Fourier Transform Using Radix-4 Butterfly Units | Chapter 2 | Emerging Trends in Engineering Research and Technology Vol. 8

 This chapter presents a design of 2048-point Split Radix Fast Fourier transformer (FFT). Radix 4Butterfly units are used in the design to enhance the power performance of the FFT. Split Radix FFT(SRFFT) are widely used configuration of FFT for the low power applications which is due to its lesser computation complexity. It has the similar signal flow graph as of radix-2/4 FFTs, therefore the address generation method is also the same. The design is further modified in this chapter to enhance the power performance by improved butterfly units in SRFFT. 2048-point SRFFT is computed using radix-4 butterfly units in this chapter which reduces the dynamic power consumption as compared to the conventional design. Simulation analysis is performed to verify the improved performance of the proposed deign.
