Abstract :
A data acquisition system combining a UNIX workstation and one or several real-time microprocessors has been designed and built for the tandem accelerator. The hardware and software options chosen for reading, processing, storing, and displaying real-time experimental data are detailed. The fixed components of the hardware architecture are the VME bus for data processing and the CAMAC system for transferring digital data. A multitask multiprocessor software based on shared memory and message passing has been developed around a mixed UNIX/pSOS kernel
