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