Abstract [en]

Many contemporary FPGAs have introduced a pre-adder before the hard multipliers, primarily aimed at linear-phase FIR filters. In this work, structural modifications are proposed with the aim of reducing the LUT resource utilization and, finally, using the pre-adder for implementing single path delay feedback pipeline FFTs. The results show that two thirds of the LUT resources can be saved when the pre-adder has bypass functionality, as in the Xilinx 6 and 7 series, compared to a direct mapping.
