This paper reports that for nuclear physics experiments at the internal and external beam of the Julich Cooler Synchrotron COSY, a three-level data processing and acquisition system is developed. Signals from various detector arrangements are digitized and preprocessed by CAMAC, FASTBUS and VME modules. A multiprocessor system based on VME bus is used for event-building, data recording and buffered data transfer to the host computer. All crates are connected by parallel VICbus. For this, an intelligent CAMAC crate controller with VICbus is under development. Microcomputer-based VME modules are equipped with CPU's of the 680XO family, working under OS-9 real-time operating system. The data acquisition system is mainly based on commercially available modules. For experiment control and data analysis, workstations as part of a local cluster are provided. Proprietary standards developed at CERN, together with OSF open standards will be implemented. TCP/IP protocols for VMEbus masters and host computer serve for initialization and command transfer.
