Multipliers are the fundamental arithmetic unit in multimedia and digital signal processing applications. The fixed width multipliers are used in those applications where the authors have to maintain a fixed format and allow a little accuracy loss of output data. In this paper, they have proposed a low power technique for high speed modified booth multiplication. Even though modified booth multiplier reduces truncation error it consumes more power for the purpose and reduces speed. To reduce power consumption in truncation process they introduce error tolerant adder in modified fixed width Booth multiplier.
