Trigger generation • Permanent checking of time interval • Programmable Time interval • Programmable number of pixels • Programmable number of clusters • Wait for first events • Programmable Time interval • Programmable number of pixels • Programmable number of clusters
Pixel processing algorithm • Accept events in coincidence interval (programmable) • Find number of active pixels • If min<N>max check position of pixels • Check number of clusters • Check Amplitude of signals, if for all clusters Amplitude > max – reset and wait for new event • If some clusters have Amplitude < max -- create telemetry packet, save or transmit to SC • Wait for next GRB?
