Online tracking and data processing with 14k processors in the first ALICE TRD supermodule — •Venelin Angelov for the ALICE TRD collaboration — KIP, University of Heidelberg, 69120 Heidelberg, Im Neuenheimer Feld 227

The first supermodule of the Transition Radiation Detector (TRD) of the ALICE experiment was built and tested in 2006. The presentation will give a short overview on the digital electronics there and will go deeper into selected topics: 1) The production and testing of the TRAcklet Processor chips (TRAP) as well of the Optical Readout Interface (ORI); 2) Online tracking and digital data processing with about 14400 processors in about 3600 TRAP chips; 3) Fast low latency data readout off the detector consisting of readout tree running at 120MHz DDR and 60 optical links at 2.5GBit/s.
