The CBM-TRD Data Processing Board Firmware — •David Schmidt for the CBM collaboration — Infrastructure and Computer Systems in Data Processing, Frankfurt, Deutschland

The Compressed Baryonic Matter (CBM) experiment at the Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany, is a fixed target heavy-ion physics experiment. The goal of the experiment is to probe the QCD phase diagram at very high net-baryon densities and moderate temperatures. The SIS-100 accelerator will provide a high luminosity heavy-ion beam, which allows for the measurement of particles with very low production cross sections. CBM is designed without a hierarchical trigger system, therefore self-triggered radiation hard readout electronics are required to cope with interaction rates of up to 10 MHz. The Transition Radiation Detector (TRD) employs the SPADIC 2.2 as the readout ASIC, featuring 32 channels and two GBTx e-links. The timestamped hit messages from the SPADIC have to be processed in the TRD-DPB (Data Processing Board) to be compatible with the CBM microslice readout. A microslice contains all the self-contained data in a given timeframe from a detector sub-system. An overview of the TRD-DPB firmware and in particular the data processing will be given.
