Read-Out Receiver Card Upgrade for ALICE DAQ and HLT — •Heiko Engel and Udo Kebschull — Infrastruktur und Rechnersysteme in der Informationsverarbeitung (IRI), Institut für Informatik, Goethe-Universität Frankfurt am Main

In the ALICE read-out chain, both Data Acquisition (DAQ) and High Level Trigger (HLT) use FPGA-based Read-Out Reveicer Cards (RORCs) as interface between the optical Detector Data Link (DDL) and the DAQ and HLT cluster machines. A new version of this card has been developed as a common project of both groups. This card features a fast PCI-Express interface and parallel optical links controlled by a Xilinx Virtex-6 FPGA. This new board provides compatibility with the current read-out architecture while allowing read-out upgrades required for some systems after LS1. First boards are available and are under test. This contribution will present the state of the project.
