The Universe II Advantage
The Tundra Universe II is the industry’s leading high performance
PCI-to-VMEbus interconnect. Universe II is fully compliant with the
VME64 bus standard, and is tailored to support the next-generation of
advanced PCI processors and peripherals. With a zero wait state
implementation for write transactions, and the capability to support
prefetch reads and multi-beat transactions, the Universe II provides
high performance on the PCI bus.
The Universe II eases development of VMEbus systems by providing
direct connection to a local PCI bus. The device is ideally suited for
CPU or peripheral boards functioning as both master and slave in the
VMEbus system. Bridging is accomplished through a decoupled
architecture with independent FIFOs for inbound, outbound, and DMA
traffic. With this architecture, throughput is maximized without
sacrificing bandwidth on either bus.
With the Universe II, you know that as your system becomes more
complex, you have proven silicon that continues to provide everything
you need in a PCI-to-VME bridge.

Typical Application: Single Board Computers
The Universe II is widely used on VME-based Single Board Computers
(SBC) that employ PCI as their local bus and VME as the backplane
bus, as shown in the accompanying diagram. These SBC cards support
a variety of applications including telecom, datacom, medical,
industrial, and military equipment.
The Universe II high performance architecture seamlessly bridges the
PCI and VME busses, and is the VME industry’s standard for single
board computer interconnect device.
