Distributed modular RT-systems for detector DAQ, trigger and control applications

Abstract

A modular approach to development of distributed modular system architecture for detector control, data acquisition and trigger data processing is proposed. A multilevel parallel-pipeline model of data acquisition, processing and control is proposed and discussed. Multiprocessor architecture with SCI-based interconnections is proposed as good high-performance system for parallel-pipeline data processing. A network (Ethernet -100) can be used for loading, monitoring and diagnostic purposes independent of basic interconnections. The modular cPCI-based structures with high speed modular interconnections are proposed for DAQ and control applications. For distributed control RT-systems, to construct the effective (cost-performance) systems the same platform of an Intel compatible processor board should be used. The basic computer multiprocessor nodes consist of high-power PC MB (Industrial Computer Systems), which are interconnected by SCI modules and link to embedded microprocessor-based sub-systems for control applications. The required number of multiprocessor nodes should be interconnected by SCI for parallel-pipeline data processing in real time (according to the multilevel model) and link to RT-systems for embedded control.
