Pipelined FFT

General Description

Comcores Pipelined Fast Fourier Transform (FFT) IP core is an implementation of a Cooley-Tukey FFT algorithm, a computationally efficient method for calculating the Discrete Fourier Transform (DFT). The FFT uses a Radix-2, Decimation-In-Time (DIT) and pipelined architecture targeting high performance systems where high throughput is a key requirement. The core comes with a large variety of run-time configurations such as FFT/IFFT mode and transform size which makes it suitable for a large variety of applications such as OFDM systems (e.g. LTE or New Radio) and real-time signal analysis. For any high performance application the FFT IP core delivers on your need for speed and performance whether the target is FPGA or ASIC.
