Study and Analysis of Different Parameters and Power Consumption of Various Multipliers in FIR Filter using VHDL

Sushant Shekhar, Ghanshyam Jangid

Abstract: Power consumption and speed are the two main performance criterion of any circuit in VLSI system design. A multiplier and adder play an important role in VLSI technology. A circuit performance is usually explained by the performance of adder and multiplier. In digital circuit serial and parallel multiplier are used for the operation. As a result, multipliers with optimized area & speed have been designed with fully parallel algorithms. Low-power design led directly to the portable device uptime. Therefore, low power multiplier design has been in an important part of the low power VLSI system design.
