Overview
The UltraLong FFT IP Core uses an efficient Fast Fourier Transform (FFT) algorithm to provide multimillion-point discrete transforms on data frames or continuous data streams. This structure utilizes state-of-the-art off-chip memory technology and N1- and N2-length pipelined radix-2 FFT engines with an additional rotation stage to perform N=N1xN2 transform lengths, from 1K to 64M points. The core is available with any width fixed or floating point data. The UltraLong IP Core is easily targeted to current Xilinx FPGA devices and various external memory types.
Key features
- UltraLong algorithm for performing continuous Fast Fourier Transforms (FFTs)
- For transform lengths that exceed on-FPGA memory capacity
- Up to 4M points using QDR SRAM
