A Design Framework for Distributed Data Acquisition and Triggering Systems in High Energy Physics Experiments
Shebli Anvar, François Terrier
We present the first conceptual results in the design of an object-oriented framework that
tackles recurrent problems encountered when developing acquisition and triggering systems
for high-energy physics experiments. These problems include software/hardware frontier
definition and the impact of both intrinsic and performance-related distribution on software
development. Based on the UML (Unified Modeling Language) extension mechanisms and a real-time
CORBA (Common Object Request Broker Architecture) implementation, the framework aims at
providing 1) high-level concepts for flexible hardware-software separation, and 2) simple
mechanisms for transparently deriving distribution automatically from system-level definitions.
The framework will therefore implement design patterns that result from our experience of HEP
(High Energy Physics) TDAQ (Trigger and Data Acquisition) system development.
