Abstract
We have built a fast programmable trigger processor based on a state-o f-the-art Field Programmable Gate Array (FPGA) IC for the Pale Verde N eutrino Oscillation Experiment. The trigger processor can accommodate 160 ECL input signals, 8 NIM input signals, 16 ECL output signals and 8 NLM output signals. Our two-level trigger logic is designed asynchro nously to maximize speed. We have attained trigger times of 40 ns for level 1 and 100 ns far level 2 with 132 asynchronous inputs. The trigg er processor can be upgraded by replacing the FPGA with more advanced versions of tile chip as they appear.
