Abstract :
A Toroidal LHC ApparatuS (ATLAS) Trigger/Data Acquisition (TDAQ) system connects via 1600 Read-Out-Links (ROL) to the ATLAS subdetectors. Each Read-Out-Buffer (RobIn) prototype attaches to 2 ROLs, buffers the incoming event data stream of 160 MB/s each, and provides samples upon request to the TDAQ system. We present the design of the PCI-based RobIn module, which is built around a XILINX XV2V1500 field-programmable-gate-array, together with initial results from rapid prototyping studies.
