This paper presents the design and implementation of signed-unsigned Modified Booth Encoding multiplier. Thus, the requirement of the modern computer system is a dedicated and very high speed multiplier unit that can perform multiplication operation on signed as well as unsigned numbers. The conventional Modified Booth Encoding (MBE) generates an irregular partial product array because of the extra partial product bit at the least significant bit position of each partial product row. The modified Booth Encoder circuit generates half the partial products in parallel. By extending sign bit of the operands and generating an additional partial product. The Carry Save Adder (CSA) tree and the final Carry Look Ahead (CLA) adder used to speed up the multiplier operation. The resultant multiplier shows best performance than others. Since the proposed multiplier operates at GHz ranges.
