An universal read-out controller

Abstract

Since 2007 we design and develop a ROC (read-out controller) for FAIR's data acquisition. While our first implementation solely focused on the nXYTER, today we are also designing and implementing readout logic for the GET4 which is supposed to be part of the ToF detector. Furthermore, we fully support both Ethernet and Optical transport as two transparent solutions. The usage of a strict modularization of the Read Out Controller enables us to provide an Universal ROC where front-end specific logic and transport logic can be combined in a very flexible way. Fault tolerance techniques are only required for some of those modules and hence are only implemented there. © 2010 IOP Publishing Ltd and SISSA.
