Description
After a successful three-year data taking period, the Summary Trigger Unit,
a FPGA-based embedded device implementing the ALICE EMCal L1 trigger
algorithms, has demonstrated efficient real-time selection of events with high
transverse momentum jets and photons.
LHC LS1 has been the opportunity for ALICE to upgrade its calorimetry
system with DCal, a second arm situated back-to-back in azimuth to EMCal.
The
exibility and scalability of STU hardware design has then proven to
be a major asset to extend its use to both DCal and PHOS calorimeters
implementing even more complex L1 Jet Patch algorithms featuring on-line
congurable patch sizes, spatial windowing over DCal and PHOS aggregated
regions, and dynamic threshold adjustement based on median background
estimation through EMCal-DCal custom serial link communication.
The poster will present all these new STU developments for the upcoming
LHC Run 2.
