INTRODUCTION
The prolific growth in semiconductor device industry has led to the advancement of high performance
portable systems with heighten reliability in data transmission. Multiplication is a heavily used arithmetic
operation that figures distinguished in signal processing and scientific applications. Typical DSP applications
where a multiplier plays an important role include digital filtering, digital communications and spectral analysis.
Many current DSP applications are aimed at portable, battery-operated systems, so that power dissipation
becomes one of the primary design limitations. Meanwhile multipliers are quite complex circuits and must
typically operate at a high system clock rate, dropping the delay of a multiplier is a vital part of satisfying the
overall design.
The ALU is the core in DSP and ASIC where it is used in comparison, convolution, correlation, and digital
filters. An ALU combines a variety of arithmetic and logic operations into a single unit. The speed of ALU
greatly depends on its multiplier circuit. This in turn increase demand for high speed multipliers, at the same
time keeping in mind low area and moderate power consumption. Generation of partial product and their
accumulation are the two basic operation of multiplication. A binary multiplier is an electronic circuit used in
digital electronics, like a computer to multiply two binary numbers. There are different types of multiplier.
