Abstract. The bar P ANDA 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 P ANDA 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).

Key words: Data acquisition circuits; Trigger algorithms
