1. About the Unified FFT IPs

Updated for:
Intel® Quartus® Prime Design Suite 24.1
IP Version 1.0.8
The Unified FFT IPs comprise the Bit-Reverse IP, the FFT IP, the Parallel FFT IP, the Variable Size Bit-Reverse IP, and the Variable Size FFT IP.

These IP use the same high-level synthesis technology as DSP Builder. The high-level synthesis technology allows you to generate an IP that specifically targets the selected device family, speed grade, and frequency.

Altera recommends you use these Unified FFT IPs and not the FFT IP Core unless:

  • The global enable-based flow control in Unified FFT IPs is not suitable for your requirements.
  • You require 128K or 256K FFTs.
  • You require bidirectional FFTs.
  • You require an in-place or memory-based architecture for low-rate applications.
