Abstract—Wireless systems is mainly based on the Orthogonal Frequency Division Multiplexing
(OFDM).The orthogonal frequency division multiplexing is mainly used to split the input signals
into number of sub carrier signals. The orthogonal frequency division multiplexing requires an
Inverse Fast Fourier Transform (IFFT).The inverse fast Fourier transform is mainly used to
produce multiple sub-carriers signal. The FFT/IFFT processor for OFDM applications is
described in this paper. The architecture uses single path delay feedback style and it occupies
less memory space. The read only memory is mainly used to store the twiddle factors. To
eliminate the Read Only Memory (ROM) a ROM-less FFT/IFFT processor is used. The
reconfigurable complex multipliers is mainly used to achieve the ROM-less FFT/IFFT processor
and the bit parallel multipliers is mainly used for square root evaluation. The Fused Multiply Add
(FMA) operation is very important in many scientific and engineering fields. The floating point
unit increases the performance and accuracy of the floating point. The Fused Multiply and Add
unit is mainly used to reduce the latency and power.
