A trigger system in High Energy Physics Experiments (HEPE) has to decide, in few µs, if the data related to a nuclear event have to be stored or not. Normally, these data, are composed of a bit map where the track coordinates are stored. The possibility to use a suitable Fuzzy Processor for HEPE has been investigated and the simulations show that a fast fuzzy processor can solve, in many cases, the trigger problem.
