IP Cores, Inc. ships new FFT4T Streaming Multi-Channel FFT Core

PALO ALTO, Calif.  --  June 10, 2025  -- IP Cores, Inc., California, USA has announced shipment of a new multi-stream FFT IP core for systems using multichannel RF communications like GPS

"Our FFT4T core is a specialized FFT/IFFT processor intended for a situation where an RF signal is received over multiple channels in parallel and its filtering is to be performed in the frequency domain" said Dmitri Varsanofiev, CTO of IP Cores, Inc, "The core accepts one sample from each channel on each sample clock. For the processing power provided, the core is extremely compact. For example, in a configuration with 12 channels, 26-bit complex input samples and 46-bit complex outputs, the core uses less than 250K gates and 20KB of RAM buffers. The core fits nicely into, for example, a multichannel GPS system"

FFT4T

The FFT4T core is a multi-stream FFT Core, implementing a complex FFT and IFFT simultaneously over many multiplexed data streams. The core performs demultiplexing for convenience of the filtering circuitry during the FFT processing and re-multiplexes the signal during the IFFT operation.

FFT

FFT or Fast Fourier Transform is an algorithm used to compute Discrete Fourier Transform (DFT) and its inverse. The FFT converts signals from its original domain into a representation in the frequency domain, and vice versa. The primary goal is to reveal the frequency components in a signal, allowing analysis of what frequencies are dominant, their amplitudes and phases.
