This paper presents the design and simulation of signed-unsigned Radix-8 Booth Encoding multiplier. The Radix-8 Booth Encoder circuit generates n/3 the partial products in parallel. By extending sign bit of the operands and generating an additional partial product the signed of unsigned Radix-8 BE multiplier is obtained. The Carry Save Adder (CSA) tree and the final Carry Look ahead (CLA) adder used to speed up the multiplier operation. Since signed and unsigned multiplication operation is performed by the same multiplier unit the required hardware and the chip area reduces and this in turn reduces power dissipation and cost of a system. The simulation is done through Verilog on xiling13.3 platform which provide diversity in calculating the various parameters.
