Overview

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.

Key features

  • Radix-2 Fast Fourier Transform processor IP Core.
  • Same IP core may be used to compute both FFT and IFFT transforms without any complexity overhead.
  • Highly parameterizable/scalable design using generic I/O fixed point precision and generic internal calculations precision.
  • Bit true Matlab script model is provided to aid core fixed point precision configuration for any target application.
  • Tested against Matlab FFT and IFFT functions the ntFFT core produces fixed point numerical results with mean absolute error in range of 1e-4. The core may be parameterized for greater internal fixed point precision to lower the mean absolute error further.
  • Final fixed point scaling to avoid precision loss is performed internally.
  • Highly programmable design supporting all power of 2 FFT/IFFT transforms in range [8,…,MAX_NFFT], where MAX_NFFT=[8,…,8192]. Support for any power of 2 higher than 8192 is also possible.
  • Parameterized architectural parallelism level to meet any target application by tuning an efficient trade-off between utilized resources and maximum throughput rate.
  • Overclocked main memory at 2x rate to achieve minimum memory resources utilization.
  • Simple yet robust interface for optimum and efficient data flow control.
  • Optional AXI4-Stream protocol interface support.
  • Synchronous clock design.
  • Silicon proven in ASIC and FPGA technologies for a variety of applications.
