Tile Computer-on-Module for the ATLAS Tile Calorimeter Phase-II upgrades

Abstract The Tile PreProcessor (TilePPr) is the core element of Calorimeter (TileCal) off-detector electronics for High-luminosity Large Hadron Collider (HL-LHC). TilePPr comprises FPGA-based boards to operate and read out TileCal on-detector electronics. Computer on Module (TileCoM) mezzanine embedded within carry three main functionalities. These include remote configuration FPGAs, interface with ATLAS Trigger Data Acquisition (TDAQ) system, interfacing Detector Control System (DCS) by providing monitoring data. TileCoM a 10-layer board Zynq UltraScale+ ZU2CG processing data, components integrate power supply be connected Advanced Telecommunication Computing Architecture carrier. A CentOS Linux deployed implement required functionalities HL-LHC. In this paper we present hardware firmware developments system in terms programming, TDAQ DCS system.
