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. Figure 2: Universe II In Single Board Computer Application Typical Applications The Universe II eases the development of VME Single Board Computers (SBCs) and I/O peripheral boards which target the following market segments: * * * * * Telecommunications Industrial Automation Medical Military Aerospace Processor Memory PMC Connection Processor Bus Processorto-PCI Bridge PCI Bus 32-bit / 64-bit Data 33 MHz I/O Controller Universe II 64-bit Data VMEbus 8091142_TA001_01 Design Support Tools Tundra understands your design challenges and works to help you overcome them.
