Development of the readout for the IBL Upgrade Project of the ATLAS Pixel Detector

The LHC luminosity is upgraded in several phases until 2022. The resulting higher occupancy degrades the detector performance of the current Pixel Detector. To provide a good performance during the LHC luminosity upgrade, a fourth pixel layer is inserted into the existing ATLAS Pixel Detector. A new FE-I4 readout chip and a new data acquisition chain are required to cope with the higher track rate and the resulting increased bandwidth. Among others, this includes a new readout board: the IBL ROD. One component of this board is the DSP which creates commands for the FE-I4 chip and has to be upgraded as well. In this thesis, the first tests of the IBL ROD prototype are presented. A correct communication of the DSP to its external memory is verified. Moreover, the implementations for an IBL DSP code are described and tested. This includes the first configuration of the FE-I4 with an IBL ROD. In addition, a working communication with the Histogrammer SDRAM and the Input FIFO on the IBL ROD are demonstrated.
