Abstract	The Large Hadron Collider (LHC) has envisaged a series of upgrades towards a High Luminosity LHC (HL-LHC) delivering five times the LHC nominal instantaneous luminosity. In particular, the ATLAS Tile Hadronic Calorimeter (TileCal) will replace completely on- and off-detector electronics using a new read-out architecture. The detector signals will be digitized by the on-detector electronics and transferred to the TileCal PreProcessors (TilePPr) located off-detector which provides interface with the ATLAS trigger and data acquisition systems. FELIX is the ATLAS common hardware platform designed to act as a data router. However, a software data handler Read-Out Driver (SWROD) element will perform detector specific data processing without data buffering including configuration, calibration, control, and monitoring. In this contribution we will present the TileCal read-out strategy for the HL-LHC, a detailed description of the PPr interface with the FELIX and the tests performed with the PPr and FELIX prototypes in the testbench and in the demonstrator installed in the ATLAS cavern.
