Abstract

The Muon-to-Central-Trigger-Processor Interface is part of the Level-1 trigger system of the ATLAS experiment at the Large Hadron Collider at CERN. The upgrade of the Muon-to-Central Trigger Processor Interface will be described. It will use optical input and provide full precision region-of-interest information for muon candidates to the topological trigger processor of the Level-1 trigger system. The new Muon-to-Central-Trigger-Processor Interface will be implemented as an ATCA blade receiving 208 optical serial links from the ATLAS muon trigger detectors. Two high-end processing FPGAs will eliminate double counting of identical muon candidates in overlapping regions and send candidate information to the topological trigger and multiplicities to a third FPGA which will combine the candidate information, send muon multiplicities to the Central Trigger Processor and provide readout data to the ATLAS data acquisition system. A System-on-Chip module will provide communication with the ATLAS run control system for control, configuration and monitoring of the new Muon-to-Central-Trigger-Processor Interface.
