The modified cabin multiplier is one of the different techniques for signed multiplication. It is normally used as the fastest multiplier. Baugh Wooley Multiplier is another technique for sign multiplication. It is not widely used because of its complexity of structure. Here, the design and implementation of the modified 8-bit booth multiplier and the Baugh Wooley multiplier have been done using the conventional method as well as using the high performance multiplier reduction (HPM) tree technique. Comparative analysis of the entire design for delay, area foot print and power has been made using Cadien 180nm RTL complier to demonstrate that Baugh Wooley multiplier may be faster than the modified booth multiplier.
Multiplication is one of the complex arithmetic operations. In most signal processing algorithms multiplication is a root operation whereas multipliers have large area, consume considerable energy and long latency. Therefore, in the design of the low power VLSI system, the low power multiplier design is also an important part. Most of the parallel multiplier architecture can be classified into three parts: primary partial product bit generation using simple AND gateways or through the use of any recoding strategy; Partial product bit using any irregular matrix of logarithmic tree or using a regular array; And the final addition.
The increasing importance of the portable system and the need to limit power consumption in high density ULSI chips have led to rapid and innovative developments in low power design. The need for a low-power design is becoming a major problem in high-performance digital systems such as microprocessors, digital signal processing and other applications. As demand for portable computing and communication grows, the energy efficiency multiplier plays an important role in the design of the large-scale integration system (VLSI). Multiplication is one of the essential operations in many algorithms used in Digital Signal Processing (DSP). A major requirement of the high-performance digital system is high-speed multiplication. In many cases, the multiplier may be present in the critical path and the processing speed is ultimately reduced by the multiplication rate. The Multiplier algorithm is also one of the main contributors to total power dissipation. Reducing energy dissipation is a key criterion in multiplier design.
