EVENT BUILDER.A large switchingnetwork (512+512 ports) with a total throughput ofapproximately 500 Gbit/s forms the interconnectionbetween the sources (Readout Dual Port Memory)and the destinations (switch to Farm Interface). TheEvent Manager collects the status and request ofevent filters and distributes event building commands(read/clear) to RDPMs

EVENT FILTER. It consists of a set of highperformance commercial processors organized into manyfarms convenient for on-line and off-line applications.The farm architecture is such that a single CPUprocesses one event
