Part of Workshop on fast Cherenkov detectors – Photon detection, DIRC design and DAQ (DIRC2009)

The bar PANDA experiment will not use any hardware trigger, i.e. all raw data are streaming in the data acquisition with a bandwidth of ≤ 280 GB/s. The bar PANDA Online System is designed to perform data reduction by a factor of simeq 800 by reconstruction algorithms programmed in VHDL (Very High Speed Integrated Circuit Hardware Description Language) on FPGAs (Field Programmable Gate Arrays).
