摘要：
The Global Trigger is the final step of the CMS Level-1 Trigger. Previously implemented in VME, it has been redesigned and completely rebuilt in MicroTCA technology, using the Virtex-7 FPGA chip family. It will allow to implement trigger algorithms close to the final physics selection. The new system is presented, together with performance tests undertaken in parallel operation with the legacy system during the initial months of Run II of the LHC at a beam energy of 13 TeV.
