Machine learning evaluation in the Global Event Processor FPGA for the ATLAS trigger upgrade
Zhixing Jiang, Scott Hauck, Dennis Yin +7
The Global Event Processor (GEP) FPGA is an area-constrained, performance-critical element of the Large Hadron Collider's (LHC) ATLAS experiment. It needs to very quickly determine…
