Fixed Point FFT/IFFT IP core
4DSP’s fixed point FFT cores are the most efficient and fastest available in the FPGA world. With a revolutional architecture for efficient memory usage and balanced use of arithmetic and logic resources, we offer complete FFT solutions with any input resolution up to 2GSPS. Whether you require a forward FFT, Inverse FFT, a 2D FFT, correlation or any algorithm efficiently performed with a Fourier transform, our technology will offer you the best solution for a cost effective implementation.
Smart IP solutions increase board efficiency and reduce the price of Digital Signal Processing systems!
