FFT Compiler IP Core

Offers Two Implementation Modes: High Performance (Streaming I/O) and Low Resource (Burst I/O)

Related Products

The Lattice Semiconductor Fast Fourier Transform (FFT) Compiler IP Core offers forward and inverse FFTs for point sizes from 64 to 16384. The FFT Compiler IP Core can be configured to perform forward FFT, inverse FFT (IFFT), or port selectable forward/inverse FFT. It offers two modes of implementation: High Performance (Streaming I/O) and Low Resource (Burst I/O).

Resource Utilization details are available in the IP Core User Guide.

Features

  • Wide range of point sizes: 64, 128, 256, 512, 1024, 2048, 4096, 8192, and 16384
  • Choice of high-performance (streaming I/O) or Low Resource (burst I/O) versions
  • Run-time variable FFT point size
  • Forward, inverse, or port-configurable forward/inverse transform modes
  • Choice of no scaling, fixed scaling (RS111/RS211), or dynamically variable stage-wise scaling
