Universe II  (2401)
VMEbus-to-PCI Bus Bridge

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 33MHz.



A zero-wait state implementation, with multi-beat transactions and support for bus parking, ensures that 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.
