Rapidly growing technology has increased the demand for digital signal processing applications that are fast and effective in real-time. One of the basic operations frequently required in these applications is the multiplication operation. There is a need to develop a multiplier with high speed, less area, and low power consumption to improve its performance. One of the fastest multiplier circuits is the Radix-4 Booth multiplier. Booth encoder reduces the number of partial products and hence the number of additions. The pipeline scheme is one of the most used designs to accelerate the multiplier performance. In this paper, two designs are presented. The first proposed design aims to reduce the delay of the multiplication operation of a 16 × 16 multiplier. This design uses a pipeline scheme differently by partitioning the input into two parts and overlapping their processing. The second proposed design reduces the multiplier area by applying enhancements in the modified booth encoder circuit. The proposed circuits are synthesized using XILINX ISE 14.7 and realized using ML605 Virtex 6 FPGA board. The first proposed design achieves higher speed, lower power consumption, and less area than the prior design. The second proposed design achieves more area and power consumption reduction
