Abstract

The paper describes a concept for implementing a combined data collecting, control and trigger system for Large Hadron Collider experiments at CERN. The system, called SWIPP, is based on a flexible interconnection of fast crossbar switches, interfaced to various transducer, storage and computer nodes by Protocol Engines. This infrastructure offers a common framework for various kinds of information, being programmable and scalable in an easy way. It endeavours to solve the extremely demanding instrumentation needs of these experiments in particle physics
