摘要

In the NA62 experiment at CERN, the intense flux of particles requires a high-performance trigger for the data acquisition system. A Level 0 Trigger Processor (LOTP) was realized, performing the event selection based on trigger primitives coming from sub-detectors and reducing the trigger rate from 10 to 1 MHz. The LOTP is based on a commercial FPGA device and has been implemented in two different solutions. The performance of the two systems are highlighted and compared. (C) 2015 Elsevier B.V.
