Two-Chip VLSI Architecture for Real-Time SETI Signal Processing: DFT Engine and CAM-Based Pattern Detection
To the point
Researchers J. F. Duluk, I. R. Linscott, A. M. Peterson (Stanford), J. Burr, B. Ekroot, and J. Twicken built two custom VLSI chips to power SETI’s real-time radio signal search, with one performing fast Fourier transforms for spectrum analysis and the other using a memory-based processor for pattern detection, making the hardware compact and cheaper.
