Abstract :
A three-level data processing and acquisition system is being developed. Signals from various detector arrangements are digitized and preprocessed by CAMAC, FASTBUS, and VME modules. A multiprocessor system based on VMEbus 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 rate controller with VICbus is under development. Microcomputer-based VME modules are equipped with CPUs of the 680X0 family, working under the OS-9 real-time operating system. The data acquisition system is mainly based on commercially available modules
