摘要：
To continue triggering with the current performance in the Large Hadron Collider's Run 2, the Global Muon Trigger (GMT) of the Compact Muon Solenoid experiment will have to undergo a significant upgrade. In this upgrade the GMT will be reimplemented in a Xilinx Virtex-7 card utilizing the microTCA architecture. The available high-capacity input and output will be used to increase the number of sent and received muon objects. Furthermore their data size will increase from currently 32 bits to 64 bits per object. Additionally the GMT will calculate a muon's isolation using energy information received from the calorimeter trigger. This information is added to the muon objects forwarded to the Global Trigger. It may also be possible to migrate the final sorting stage of each muon subsystem to the GMT using the increased bandwidth and processing power. A summary of the current status of the future GMT's development will be given.
