Comparison of Different Types of Multipliers with Respect to Speed, Area and Power
Nowadays, digital circuits play a vital role while designing of DS (Digital Signal) Processor, graphical systems,
FPGA/ASIC, multimedia systems.An increasing number of high speed DSP applications, need of high precision (16-bit or
more) fixed or floating point multiplier suitable for VLSI implementation. In this paper I concentrated mainly on design of
digital circuits which occupies less area, high speed performance which consumes less power. For example, one of the
versatile digital circuit is “Multiplier”. I emphasizing the multiplier circuit because of system performance, generally
determined by the performance of the multiplier. Multiplier is a fundamental unit of digital system and signal processing.
Multiplier and adder are basic arithmetic unit of digital systems and signal processing. Major problem in multiplier shows in
terms of speed, power, area and complexity. High speed DSP computation applications such as Fast Fourier Transform
(FFT) requires addition, multiplication because as large number of filtration, convolutions and related operations are needed
during the Digital Signal Processing. Now days. Modern computer system requires the high speed performance
multiplication for signed, un signed numbers. Multiplier is also essential for all types of wireless communications
applications. In this novel I compared all different types of multiplier their performance in terms of speed, area and power.
For this I used Xilinx ISE 14.5 version.
