Currently, both DAQ and HLT independently use
Read-Out Receiver Cards (RORCs) to read out the detector data. Both
cards provide a PCI-X Interface and two optical links. These cards
transfer the data received from the optical links to the host memory
using DMA and perform controlling and preprocessing. As PCI-X gets
obsolete, a new common RORC for both HLT and DAQ will be developped.
This card will be based on a Xilinx Virtex-6 FPGA with 8 lanes PCIe Gen2
and 12 bidirectional optical links up to 6.6 Gbps per channel
