As powerful 32-bit microprocessors begin operating in multiprocessor systems, two revamped buses will be competing to move the data. The vmebus, recently upgraded with the expansion vmxbus and a serial vmsbus by a team lead by motorola and signetics, will be going head to head against intel's multibus ii in the 32-bit arena. Both buses have full 32-bit primary data and addressing paths, but multibus ii uses multiplexing to achieve what the vmebus does with dedicated addressing and data lines. Data-transfer rates for both are faster than 40 megabytes a second, but multibus ii uses a synchronous timing scheme while vme runs asynchronously. Their most important common attribute is their open-system architecture.
