An ATCA and FPGA-based Data Processing Unit for PANDA Experiment

An ATCA and FPGA-based Data Processing Unit for PANDA Experiment has been developed. The Unit features 5 Xilinx Virtex-4 FX60 FPGA chips and up to 10 GBytes DDR2 memory. High bandwidth connectivity is provided by 8 additional optical links using RocketIO ports and 5 Gbit Ethernet links to receive data from front-end electronics and transmit the data passed high level trigger to mass storage. A single ATCA shelf can host up to 14 boards which are interconnected via a full mesh backplane. A prototype system has been set up and some tests have been made.
