Streaming pipelined FFT

Overview

A highly efficient pipelined radix-2 squared FFT. Ported to both ASIC and FPGA technology and achieving a very high clock speed with minimal logic and memory.

Also available is a variant with single bit width growth per stage which does not require per-sample exponents.

EnSilica has a comprehensive range of FFT IP cores, these cores can be configured to replace the AMD FFT LogiCORE™ IP or FFT Intel® FPGA IP Core when migrating an FPGA design to ASIC technology.

Key Features

  • 1 clock cycle per point, no gap required between packets
  • Run-time selection of any power of 2 FFT points
  • Run-time selection of forward or inverse transform
  • Internal convergent rounding
  • AXI4 streaming interface
  • Per sample exponent for maximum dynamic range
  • Parameterized maximum transform length
