Roadmap for VME Technology

VME Technology fits into 4 categories: core parallel bus, interconnects and fabrics, mezzanines, and support. The VME Technology Family diagram below shows these categories with the specifications as they develop over time.
Core Parallel Bus TechnologyThe parallel bus continues to evolve, from the original VME32 circa 1982 to the latest VME2eSST. The addition of serial fabrics to enhance the parallel bus is reflected in today's activity on VME Switched Serial and V.46 efforts. |
Interconnect and Fabric TechnologyWhile the VMEbus itself has substantial bandwidth, designers have sought faster, dedicated channels for tasks with intensive data movement. VSB, SKYchannel and RACEway were some of the parallel bus options developed. Today's specifications use serial fabrics, such as Gigabit Ethernet on VME64x and newer serial fabrics called for in VXS and V.46. |
