Bustronic is your resource for the latest in the development of next-gen backplanes and systems. On a periodic basis, we will post news and advancements in the StarFabric (PICMG 2.17), Compact Packet Switching (cPSB, PICMG 2.16), Serial Mesh (PICMG 2.20), VXS (VITA 41), AdvancedTCA (PICMG 3.x), VME320, and optical backplanes.
General Micro Systems OmniVME is a VME-to-PCI bridge device that provides an interface between a VMEbus (or VME320) backplane and a local on-card PCI bus. OmniVME supports 16-, 32-, and 64-bit VMEbus transfers and can act as a master or slave with full Slot One system control functionality. It also supports 2eSST signaling (transfers data on both edges of each VMEbus clock), which enables it to move data over a 21-slot VME320 backplane at a sustained data rate of 1 Giga byte/sec. That's more than ten times faster than the 80 Mbyte/sec theoretical maximum supported by VME64 and 10-20 times faster than the 20-30 Mbyte/sec data rate supported by similar devices. Moreover, these high-speed data transfers can occur concurrent with standard 16-, 32-, and 64-bit transfers, thereby enabling high-speed VME320 cards to coexist with legacy VMEbus cards on the same backplane.
