The ReadOut Subsystem (ROS)
The ReadOut Subsystem (ROS) is part of the dataFlow subsystem of the ATLAS Trigger & DAQ. It provides for subdetector data reception, via ReadOut Links (ROLs), buffering and distribution.
The ROS software
The ROS software is a multi-threaded Object Oriented application written in C++. Members of the UCL group were heavily involved in the design and implementation and are responsible for the core classes of the software.
The ROS software framework is also used for the ROD Crate DAQ (RCD).
Modelling the ROS
As well as contributing to the actual software of the ROS, the UCL group are also responsible for providing a software model of the ROS as part of the at2sim simulation of the ATLAS Trigger/DAQ.
