Abstract :
The VXIbus standard defines the basic hardware and communications protocols for instrument-on-a-card systems. One important systems architecture that builds on VXI is based on local area network, UNIX-related technologies and an object-oriented software bus. The heart of the system is an embedded VXIbus processor for controlling the test system and implementing virtual instruments. The software bus concepts of its multitasking operating system make it possible to create or delete software packages dynamically and to control the measuring resources. The system has rigorous control over dynamic resource allocation and is garbage-collection-free
