Description

The Muon to Central Trigger Processor Interface (MUCTPI) of the ATLAS experiment at the
Large Hadron Collider (LHC) at CERN is being upgraded for the next run of the LHC in order
to use optical inputs and to provide full-precision information for muon candidates to the
topological trigger processor (L1TOPO) of the Level-1 trigger system. The new MUCTPI is
implemented as a single ATCA blade with high-end processing FPGAs which eliminate double
counting of muon candidates in overlapping regions, send muon candidates to L1TOPO,
and muon multiplicities to the Central Trigger Processor (CTP), as well as readout data to
the data acquisition system of the experiment. A Xilinx Zynq System-on-Chip (SoC) with a
programmable logic part and a processor part is used for the communication to the processing
FPGAs and the run control system. The processor part, based on ARM processor cores, is running
embedded Linux prepared using the framework of the Linux Foundation's Yocto project. The
ATLAS run control software was ported to the processor part and a run control application
was developed which receives, at configuration, all data necessary for the overlap handling
and candidate counting of the processing FPGAs. During running, the application provides
ample monitoring of the physics data and of the operation of the hardware.
