The PreProcessors for the ATLAS Tile Calorimeter Phase II Upgrade

The Large Hadron Collider has envisaged a series of upgrades towards a High Luminosity LHC delivering five times the LHC nominal instantaneous luminosity. The ATLAS Phase II Upgrade will accommodate the detector and data acquisition system for the HL-LHC. In particular, the Tile Hadronic Calorimeter will completely replace front-end and back-end electronics using a new read-out architecture. The digitized detector data will be transferred for every beam crossing to the PreProcessors located in off-detector counting rooms with a total data bandwidth of roughly 80 Tbps. The TilePPr implements larger pipelines memories and must provide pre-processed digital trigger information to Level 0/1 trigger systems. The TilePPr system represents the link between the front-end electronics and the overall ATLAS data acquisition system. It also implements the interface between the Detector Control System and the frontend electronics which is used to control and monitor the high voltage distribution system. The TilePPr is responsible of transmitting the commands to configure, control and monitor the front-end electronics.
