AMD AI-Engines in fixed latency environments / Xiotidis, Ioannis (CERN) /ATLAS Collaboration
The ATLAS Level-0 Global Trigger is a mission critical system opting to take advantage of the full calorimeter granularity during Run-4 and beyond. Level-0 Global will be executing a cascade of trigger algorithms combined both the calorimeter information and the muons. [...]

The Phase-1 Upgrade of the ATLAS level-1 calorimeter trigger / Carroll, Anthony Maurel (University of Oregon (US)) ; ATLAS TDAQ Collaboration /ATLAS Collaboration
The ATLAS level-1 calorimeter trigger is a custom-built hardware system that identifies events containing calorimeter-based physics objects, including electrons, photons, taus, jets, and missing transverse energy. In Run 3, L1Calo has been upgraded to process higher granularity input data. [...]

GELATO: A Generic Event-Level Anomalous Trigger Option for ATLAS in LHC Run 3 / Sugizaki, Kaito (University of Pennsylvania (US)) ; ATLAS Collaboration /ATLAS Collaboration
Search for physics beyond the Standard Model has been a long-standing subject at the LHC. The absence of such signatures indicates that new physics may elude standard triggers; conventional triggers at the ATLAS experiment are constructed by setting thresholds on variables such as the particle momentum, targeting event topologies exclusive to specific models.

The upgrade of the ATLAS Trigger and Data Acquisition system for the High Luminosity LHC / Wengler, Thorsten (CERN) ; ATLAS Collaboration /ATLAS Collaboration
The ATLAS experiment at CERN is constructing upgraded system for the "High Luminosity LHC", with collisions due to start in 2030. In order to deliver an order of magnitude more data than previous LHC runs, 14 TeV protons will collide with an instantaneous luminosity of up to 7.5 x 10e34 cm^-2s^-1, resulting in much higher pileup and data rates than the current experiment was designed to handle. [...]

Status and testing of the MDT Trigger Processor for the ATLAS Level-0 Muon Trigger at HL-LHC / Longarini, Iacopo (University of California Irvine (US)) /ATLAS Collaboration
The Monitored Drift Tube Trigger Processor (MDT-TP) will improve the rate capabilities of the first-level muon (L0 Muon) trigger of the ATLAS Experiment during the operation of the HL-LHC. The information of the trigger candidate, obtained by other muon trigger subsystems, will be combined with the precision of the MDT chambers in order to improve the resolution on the muon momentum measurement, while limiting the trigger rate to an acceptable level in the high-pileup environment of HL-LHC. [...]

QDIPS: Deep Sets Network for FPGA investigated for high speed inference on ATLAS / Antel, Claire (Universite de Geneve (CH))
We adapted DIPS (Deep Impact Parameter Sets), a deep sets neural network flavour tagging algorithm previously used in ATLAS offline low-level flavour tagging and online b-jet trigger preselections, for use on FPGA with the aim to assess its performance and resource costs. [...]

Online track reconstruction with graph neural networks on FPGAs for the ATLAS experiment / Dittmeier, Sebastian (Heidelberg University (DE))
For the HL-LHC upgrade of the ATLAS TDAQ system, a heterogeneous computing farm deploying GPUs and/or FPGAs is considered to be used for the Event Filter system, together with the use of modern machine learning algorithms such as Graph Neural Networks (GNNs) to solve computationally complex tasks within that system.
