The ATLAS detector produces a huge data stream that is read out via 1,600 lines and stored until interesting events are forwarded for further analysis. Due to the required high speed, ATLAS uses 600 special computing devices, 4 of them in one PC each. These boards are configured by software to operate as application-specific hardware processors.
By reprogramming, these boards can also do completely different things: Based on an ATLAS development, a spin-off company, Silicon Software GmbH (www.silicon-software.com) offers such systems for low-cost, high-performance industrial image processing. One example is real-time control of laser welding during car production: 1 Mpixel images are processed at 75 Hz, corresponding to 0.5m/s inspection speed.
