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. VMEbus Interface The Universe II is the industry standard PCI bus-to-VMEbus bridge. The Tundra Universe II is the industry's leading high performance PCI-toVMEbus interconnect. Universe IIis 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. PCI Interface * Industry-proven, high performance 64bit VMEbus interconnect * Fully compliant, 32-bit or 64-bit, 33 MHz PCI bus interconnect * Integral FIFOs for write posting to maximize bandwidth utilization * Programmable DMA controller with Linked-List mode * Flexible interrupt logic * Sustained transfer rates up to 60-70 Mbytes/s 32-bit Address / 64-bit Data 33 MHz PCI Bus Features PCI Target Channel Posted Writes, Coupled Read JTAG 8091142_BK001_03 IEEE1149.1 Boundary Scan 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.
