SCI based data acquisition architectures

The scalable coherent interface (SCI) is an IEEE proposed standard (P1596) for interconnecting multiprocessor systems. The standard defines point-to-point connections between nodes, which can be processors, memories, or I/O devices. Networks containing a maximum of 64 K nodes with a bandwidth of 1 Gbyte/s between nodes can be constructed. SCI is an attractive candidate to serve as a backbone for high-speed, large-volume data acquisition systems such as those required by future experiments at the proposed Large Hadron Collider (LHC) at CERN. First results for a model of a large LHC experiment containing over 1000 nodes are reported.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
