摘要：A single precision floating-point fused add-subtract unit and fused dot-product unit is presented thatperforms simultaneous floating-point add and multiplication operations. It takes to perform a major part of singleaddition, subtraction and dot-product using parallel implementation. This unit uses the IEEE-754 single-precisionformat and supports all rounding modes. The fused add-subtract unit is only about 56% larger than a conventionalfloating-point multiplier, and consumes 50% more power than the conventional floating-point adder. The speed of thefused dot-product is about 27% faster than the conventional parallel approach. This will combine to use for FFTalgorithms mainly. The simulation results are obtained using Xilinx 14.3 EDA tool. The results show that the RTLview and synthesis reports.
