We also developped the buffer manager software for the ROBin card in which the memory management of the buffer is performed in the host PC processor, and software to deal with data requests and data distribution. We have benchmarked the switch-based ROS, to be compared with the bus-based ROS. We developed a Test Suite of programs to configure and test the ROBin cards. | ||||||||

< < | The plan is to prototype and test a new Robin compatible with PCIe, by effecting minimal changes to the current, PCI-X-compatible, design. This will allow ATLAS to rely on more modern motherboards, thus ensuring the medium-term life of the ATLAS ROS system. An essential requirement is that the new RobinExpress ROSs must be able to coexist side-by-side with the current PCI-X ROSs. | |||||||

![]() The ATLAS read-out buffer input card, designed and built at RHUL. Data Acquisition at RHULATLAS workOn ATLAS, we had a major involvement in the design, development, prototyping, testing and production of the Read Out Buffer (ROBin) cards, which are a key part of the Read Out Subsystem (ROS). The PCI-based ROBin card, which incorporates the S-LINK on the PCB is shown above. The UK production of 350 ROBin cards for ATLAS was completed in March 2006. We also developped the buffer manager software for the ROBin card in which the memory management of the buffer is performed in the host PC processor, and software to deal with data requests and data distribution. We have benchmarked the switch-based ROS, to be compared with the bus-based ROS. We developed a Test Suite of programs to configure and test the ROBin cards.RobinExpressThe current Robin design interfaces to the ROS host PC using PCI-X![]() ![]() Future Detectors work![]() DAQ proposal A current proposal for a DAQ associated with a future detector (for the next generation of accelerators) is to have the Detector Interface (DIF) connected to the Off-Detector Receiver (ODR) via a Link/Data Aggregator (LDA). The ODR would make use of the local PCI-Express card in the PC. ![]() PCI card (commercial component)
