The upcoming High-Luminosity LHC (HL-LHC) upgrade of the ATLAS Tile Hadronic Calorimeter (TileCal) includes a complete replacement of all on- and off-detector electronics with a new read-out architecture. Detector signal digitized by the on-detector electronics will be transferred to Pre-processors (PPr) located off-detector that will interface with the ATLAS trigger and data acquisition systems. The ATLAS common hardware platform FELIX is designed to act as a data router. A software data handler Read-Out Driver (SWROD) will perform detector-specific data-processing, which includes configuration, calibration, control, and monitoring, without buffering the data. We will present the ATLAS TileCal read-out strategy for the HL-LHC, a detailed description of the PPr interface with FELIX, results of tests performed with the PPr and FELIX prototypes, and in a "demonstrator" module already installed in the ATLAS cavern.
