Pattern comparator trigger algorithm: implementation in FPGA

摘要

The article describes the algorithm of finding the highest transverse momentum muon based on the signals from fast RPC detectors in CMS experiment at the LHC collider in CERN (Geneva). Very fast progress in FPGA performance makes it possible to build Pattern Comparator Processor (PAC) using this technology. Compilation and simulation of different configurations of PAC are discussed. Improved algorithm which requires smaller resources in the FPGAs is presented.
