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. Figure 1: Un...
