Abstract :
A VXIbus-based first-level triggering system for the CLAS detector at CEBAF (Continuous Electron Beam Accelerator Facility, Newport News, VA) has been designed and prototyped. It uses pipelining and a triple memory lookup to produce a deadtimeless trigger decision with an average latency of 110 ns and a jitter of 20 ns. The VXIbus Extended Start/Stop triggering protocols allow subnanosecond time synchronization
