Abstract: Power consumption and small area is very important for fabricating DSP system and high performance system, requirement of present scenario computer system is dedicated for very high speed and low power unique multiplier unit for signed and unsigned number therefore in this paper focus on unsigned number by using modified booth multiplier. The unsigned 4 bit and 8 bit implementation done by some modification in booth multiplier modified booth multiplier come out to make efficient multiplier reduce N/2 partial product. The parallel multiplier 4 bit and 8 bit modified booth multiplier does the computation using lesser adder and lesser iterative step. The implementation of unsigned 4 bit and 8 bit done in Xilinx ISE Design suite 12.1 tool by using VHDL, model Sim.
