A commercial Graphics Processing Unit (GPU) is used to build a fast Level 0 (L0) trigger system for the NA62 experiment at CERN. In particular, the parallel computing power of the GPU is exploited to perform real-time fitting in the Ring Imaging CHerenkov (RICH) detector for the L0 trigger of the NA62 experiment. Direct GPU communication using a FPGA-based board has been used to reduce the data transmission latency. The first result of multi-ring Cherenkov reconstrunction obtained during the NA62 physics run will be presented
