Abstract
In this paper, an architecture is presented for a fused floating-point three operand adder unit. This adder executes two additions within a single unit. The purpose of this execution is to lessen total delay, die area, and power consumption in contrast with traditional addition method. Various optimization techniques including exponent comparison, alignment of significands, leading zero detection, addition, and rounding are used to diminish total delay, die area, and power consumption. In addition to this, the comparison is described of different blocks in term for die area, total delay, and power consumption. The proposed scheme is designed and implemented on Xilinx ISE Design 14.7 and synthesized on Synopsis.
