Introduction
Booth’s multiplication algorithm was invented by ANDREW BOOTH in 1951.
This algorithm is particularly useful for machines that can shift bits faster than adding them.
Another improvement in the multiplier is by reducing the number of partial products generated.
It operates even with signed numbers
Booth multiplier
A multiplier has two stages.
In the first stage, the partial products are generated by the booth encoder and the partial product generator (ppg), and are summed by compressors.
In the second stage, the two final products are added to form the final product through a final adder.
Advantages
Booth multiplier operates with high speed.
It has low complexity.
Low power consumption.
It has less access time
Software tools
Tool : XILINX ISE 13.2i
Language: verilog HDL
Applications
It is arithmetic operation for DSP applications.
Such as ‘filtering ‘, and for fourier transforms.
To achieve high execution speed, parallel array multipliers are widely used .
These multipliers tend to consume most of power in DSP computations
Conclusion
Booth multiplier consumes comparatively less power and hence multiplier with booth recoding unit is designed for low power consumption
