ABSTRACT
<p><b>Abstract</b>—This paper presents a design methodology for high-speed Booth encoded parallel multiplier. For partial product generation, we propose a new modified Booth encoding (MBE) scheme to improve the performance of traditional MBE schemes. For final addition, a new algorithm is developed to construct multiple-level conditional-sum adder (MLCSMA). The proposed algorithm can optimize final adder according to the given cell properties and input delay profile. Compared with a binary tree-based conditional-sum adder, the speed performance improvement is up to 25 percent. On average, the design developed herein reduces the total delay by 8 percent for parallel multiplier. The whole design has been verified by gate level simulation.</p>
INDEX TERMS
Final adder, Booth encoding, multiple-level conditional-sum adder, and parallel multiplier.
