| Abstract | TileCal is the Tile hadronic calorimeter of the ATLAS experiment at LHC/CERN. The main components of the TileCal Read Out Driver are the DSPs placed on the Processing Unit dautherboards. This paper describes the code developed for the DSPs. The code is divided into two different parts: the first part contains the core functionalities and the second one the reconstruction algorithms. The core acts as an operating system and controls the configuration, data reception/transmission and synchronization between front-end data and the TTC information. The reconstruction algorithms implemented on the DSP are the Optimal Filtering (OF), Muon Tagging (MTag) and Missing ET calculation. The OF algorithm reconstructs the deposited energy and the arrival time of the data on every calorimeter channel. This energy is used by the MTag algorithm to tag low transverse momentum muons that may escape the ATLAS muon spectrometer Level 1 trigger whereas the Missing Et algorithm computes the total transverse energy and the projection on X and Y for the entire module that will be used by the Level 2 trigger system. Finally, some results obtained during the TileCal commissioning phase are also presented. | ||
