The hardware Event Builder for the NORDBALL

Abstract

A new Event Builder hardware module has been developed in order to increase the throughput, decrease the dead time, simplify extensions and improve testability and maintainability of the NORDBALL data acquisition system. The module allows an easy implementation of multiple level trigger schemes and, due to its parallel and pipelined architecture, is capable of collecting from the NORDBALL present electronics up to 50000 160-byte events/s.
