San Jose, Calif. A Fast Fourier transform (FFT) intellectual property (IP) core has been added to the MegaCore family. The FFT function is a parameterizeable IP core that can implement a block floating point system. The core employs an in-plane mixed radix four and two decimation in-frequency architecture, and implements any transform length that is a factor power of two. The core's control unit automatically implements partitioning between radix four and radix two passes. the core comes with the MegaWizard Plug-In Manager tool and is targeted at the Stratix family of PLDs.
