TJPRC, 2013

Recent researches in fabrication of DSP systems and high performance systems reveal the loss of performance due to strive with high area consumption and delay. The proposed method yields high performance by introducing booth multiplication algorithm to parallel multiplier. This paper culminates with a comprehensive design example of a parallel multiplier. Parallel MAC is frequently used in digital signal processing and video/graphics applications. The MAC provides high speed multiplication and multiplication with accumulative addition. This paper presents a combined process of multiplication and accumulation based on radix-4 booth encoding. In this Paper, we investigate the method of implementing the Parallel MAC with the smallest possible delay.

A low-power high-radix serial-parallel multiplier

2007 18th European Conference on Circuit Theory and Design, 2007

In this paper, we introduce a novel high-radix binary signed digit (BSD) serial-parallel multiplier suitable for low-power high-speed multiplication. The proposed N-bit×N-bit radix-16 serial-parallel multiplier can reduce the number of accumulation cycles of partial products to as much as N/4, and eliminate most of the invertion operations which consume power in a conventional multiplier in generating the partial products. Unlike other high-radix methods, the pre-multiplication in the new algorithm employs a BSD method which requires no extra adder, and thus removes the extra delay for additions which hinders other high-radix algorithms.

A low latency bi-directional serial-parallel multiplier architecture

2000

A new bi-directional bit serial-parallel multiplication architecture is presented. The proposed structure is regular and modular, and requires nearest neighbour communication links only, which makes it more efficient for VLSI implementation. Furthermore, a judicious deployment of latches in the circuit ensures that the multiplier operates on two coefficients of the multiplicand at the same time thus speeding up the process. Comparison of the new multiplier structure with previous ones has shown the superiority of the new architecture

Finally the performance improvement of the proposed multipliers is validated by implementing a higher order FIR filter.

Design Of High Performance Configurable Radix-4 Booth Multiplier Using Cadence Tools

CVR Journal of Science & Technology, 2014

Fast multipliers are crucial in digital signal processing systems. The speed of multiply operation is of great importance in digital signal processors and general purpose processors especially since the media processing took off. As the need for efficient design is increasing without compromising the performance, industry has to concentrate on the tradeoffs. Here, a modified Booth multiplier is implemented using an algorithm that reduces the number of partial Products to be generated using the fastest multiplication algorithm. In this work, 8X8 multipliers with maximum range of input from-128 to +127 and negative numbers represented in 2's complement form can be used. Booth Encoder i.e., Partial Product Generator and Hybrid adder are used for the design of modified booth multiplier to achieve minimum delay and less area.

Parallel Multiplier Accumulator Based on Radix-2 Modified Booth Algorithm

With the recent rapid advances in multimedia and communication systems, real-time signal processing like audio signal processing, video/image processing, or large-capacity data processing are increasingly being demanded. The multiplier and multiplier-and-accumulator (MAC) are the essential elements of the digital signal processing such as filtering, convolution, transformations and Inner products. There are different entities that one would like to optimize when designing a VLSI circuit. These entities can often not be optimized simultaneously, only improve one entity at the expense of one or more others The design of an efficient integrated circuit in terms of power, area, and speed simultaneously, has become a very challenging problem. Power dissipation is recognized as a critical parameter in modern the objective of a good multiplier is to provide a physically compact, good speed and low power consuming chip.

International Journal of Advancements in Research & Technology, Volume 1, Issue 6, November-2012 ISSN 2278-7763, 2012

Multipliers are key components of many high performance systems such as microprocessors, digital signal processors, etc. Optimizing the speed and area of the multiplier is major design issue which is usually conflicting constraint so that improving speed results mostly in bigger areas. A VHDL designed architecture based on booth multiplication algorithm is proposed which not only optimize speed but also efficient on energy use.

Design and Comparison of High Speed Radix-8 and Radix-16 Booth's Multipliers

Multiplier is one of the hardware block which generally occupies a significant chip area and is required to be minimized which will be fruitful to number of applications in which multiplier blocks constitute an important unit such as digital signal processing (DSP) systems or computational techniques. Battery operated systems require low power devices to be implemented which can be minimized if the hardware required for the device is reduced logically. This paper focuses the DSP applications in which multiplier is significantly used and proposes a technique that helps in reducing the hardware as well as delay leading to the rise in performance of the system thus helping in increasing the operation frequency by a significant value. A 16-bit multiplier has been designed using a radix-8 and radix-16 Booth's multiplication that reduces number of partial products.
