Description
In CMS, three independent first-level muon trigger systems identify muon candidate
tracks. The Global Muon Trigger (GMT) receives up to 16 candidate tracks and combines
them using algorithms exploiting the complementarity of the muon systems. The GMT
also correlates the muon candidate tracks with calorimeter regions in order to
determine muon isolation or confirmation by the calorimeter. The top four muon
candidates are forwarded to the Global Trigger. The GMT algorithms are implemented in
ten Xilinx Virtex-II FPGAs on a single 9U-VME board. The development of the VME board
and its firmware as well as the results of system and integration tests are presented.
