| Gigahertz FFT Rates on a 500MHz Budget |
Today’s systems often present a massive amount of very fast data at the front end that needs to be sampled and decimated quickly, typical of a system with a lot of data channels in play like satellite radio or cable head-end systems. Sample rates run into the gigahertz range, putting them outside the range of FPGA clock speeds if the constraint is one sample per clock. In this article, learn how Synopsys’ parallel FFT IP implementation allows data to be sampled and processed faster.

| Using Parallel FFT for Multigigahertz FPGA Signal Processing |
Very high-speed fast Fourier transform (FFT) cores are an essential requirement for any real-time spectral-monitoring system. As the demand for monitoring bandwidth grows in pace with the proliferation of wireless devices in different parts of the spectrum, these systems must convert time domain to spectrum ever more rapidly, necessitating faster FFT operations. This article examines the design of a parallel FFT (PFFT) with runtime-configurable transform length, taking note of the throughput and utilization numbers that are achievable when using parallel FFT.
