universe ii features pci-to-vmebus bridge ? 2003, tundra semiconductor corporation. all rights reserved. document: 8091142_fb001_01 - 1 - 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. figure 1: universe ii block diagram pci interface vmebus interface 32-bit address / 64-bit data 33 mhz pci bus ieee1149.1 boundary scan jtag vmebus slave channel posted writes, prefetched reads, coupled reads dma channel bidirectional fifo, direct/linked list mode register channel configuration registers, mailbox registers, semaphores interrupt channel interrupt handler, interrupter pci target channel posted writes, coupled read 8091862_bk001_03 32-bit address / 64-bit data vmebus vmebus arbiter fixed priority, round robin, single level modes location monitor four location montiors to support vmebus broadcast capability industry-proven, high performance 64-bit 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 the universe ii is the industry standard pci bus-to-vmebus bridge . extensive suite of vmebus address and data transfer modes automatic initialization for slave-only applications flexible register set, programmable from both the pci bus and vmebus ports full vmebus system controller support for rmws, adoh, pci lock cycles, and semaphores commercial, industrial, and extended temperature variants ieee 1149.1 jtag available packages: ? 25mm x 25mm, 361-contact dimpled ceramic bga (dbga) ? 35mm x 35mm, 313-contact plastic bga (pbga)
