Fully Configurable Radix 2 FFT/IFFT Processor

ntFFT core is a fully configurable solution that performs the FFT and IFFT transform. It is on-the-fly programmable in terms of transform size and type. It supports complex input/output and the results are output in normal order. It exhibits a highly parameterizable/scalable design using generic I/O fixed point precision and generic internal calculations precision. The core uses fixed-point 2’s complement arithmetic with internal auto scaling to avoid arithmetic overflow and simplify dynamic range management. The ntFFT IP Core employs a revolutionary parameterized architecture where the user can fine tune the level of data-path parallelism in order to achieve the optimum trade-off between silicon resources and throughput rate. The implementation is portable to various silicon technologies, with a simple interface for easy integration in SoC applications.
