IEC 60822:1988 is an international standard defining the Parallel Sub-system Bus (VSB) for the IEC 821 VMEbus architecture. Developed by ISO and the International Electrotechnical Commission (IEC), this standard addresses the integration and coordination needs of high-performance 32-bit microprocessor-based multiprocessor systems. The VSB serves as a local subsystem extension, optimizing data throughput and system performance by enabling efficient communication between processor boards, memory, and I/O components over a high-speed asynchronous bus.
The standard establishes the necessary framework and protocols for subsystem design, supporting both single and multiprocessor configurations. It outlines functional, electrical, mechanical, and protocol specifications for seamless and reliable operation within VMEbus-based environments.
IEC 60822:1988 covers critical aspects of VSB implementation and operation, including:
System Architecture
Bus Operation and Protocols
Arbitration Mechanisms
Physical and Electrical Specifications
Backplane Specifications
Standard Terminology & Symbol Reference
The IEC 60822:1988 standard finds practical application in a range of multiprocessor and embedded systems, where high throughput and flexible architecture are critical:
