VME32 is where everything started in August 1982. The original specification was sponsored by VITA and eventually standardized as IEEE 1014. It established a framework for 8-, 16- and 32-bit parallel-bus computer architectures that can implement single and multiprocessor systems. This bus includes the initial four basic subbuses: (1) data transfer bus, (2) priority interrupt bus, (3) arbitration bus, and (4) utility bus. Other architectures with other subbuses are possible within this VME framework.
