Level-1 jet trigger hardware for the ALICE electromagnetic calorimeter at LHC

The ALICE experiment at the LHC is equipped with an electromagnetic calorimeter (EMCal) designed to enhance its capabilities for jet measurement. In addition, the EMCal enables triggering on high energy jets. Based on the previous development made for the Photon Spectrometer (PHOS) level-0 trigger, a specific electronic upgrade was designed in order to allow a fast triggering on high energy jets (level-1). This development was made possible by using the latest generation of FPGA which can deal with the instantaneous incoming data rate of 26 Gbit/s and process it in less than 4 {\mu}s.
