PCI to VME Bridge
The Universe™ IID (also known as Universe II) is the industry standard PCI-to-VME bridge. Bridging is accomplished via a powerful decoupled architecture with independent FIFOs for inbound, outbound, and DMA traffic. With this architecture, throughput is maximized without sacrificing bandwidth on either bus. Universe bridges between the VME 64-bit bus to either a 32- or 64-bit PCI bus at 33 MHz.
A zero-wait state implementation, with multi-beat transactions and support for bus parking, ensure that the Universe II is never the bottleneck on the PCI bus. On the VME interface, a rich set of features ensures that the device fits within a wide range of applications. A full suite of addressing and data modes is implemented, including BLT and MBLT support. In addition, a fully featured system controller, interrupter, interrupt handler, and Linked-List DMA make the Universe II a flexible System Interconnect device.
The Universe II is known for its standards compliance, compatibility, reliability, large number of available device drivers and the stability of supply. These are just some of the reasons the device has become the industry's preferred method for connecting to the VMEbus.
