Dillon Engineering's Pipelined Floating Point FFT IP Core uses a modular radix-2 Fast Fourier Transform (FFT) architecture to provide discrete transforms on data frames or continuous data streams, with sample rate up to the maximum clock frequency. This efficient structure employs a single butterfly and a single delay feedback path per rank for low localized memory usage. Floating point math operators support a large dynamic range of data without requiring complicated fixed-point analysis. The standard Pipelined IP Core is easily scalable to any Xilinx device and customizable to suit many FFT applications.
