    General:
    The Solflower PCI-VME Adapter enables the Sun Ultra PCI-based workstation to connect to a wide range of existing VMEbus peripherals. The adapter includes a Solaris™ 2.5.1 - 2.8 software driver which allows peripheral devices on the VMEbus to interact transparently with the host. All software written for current VME applications can be utilized without modification in the Solaris 2.x environment.

    Product Description:
    The Solflower PCI-VME Adapter is built with a Universe 2™ single chip PCI-VME interface. The Universe uses built-in FIFO to decouple the transfer of data between the asynchronous VME and the synchronous PCI bus. The advantage of a decoupled system is increased bandwidth and a decrease of local bus latency. There is no waiting for remote bus arbitration and data acknowledgment; therefore, each bus operates at its optimum speed. By using the Solflower PCI-VME bridge, system integrators can now rely on a product which allows direct connection of all off-theshelf VME interfaces to the Sun Ultra PCI-based workstation.

    The Solflower PCI-VME Adapter consists of a board set connected via a round shielded cable (two, four, six up to 24-foot length). One board PCI card (PCI-810-07) uses a single PCI slot of the host, the other board 6U VME interface board (PCI-810-06) is installed in a VME card cage. The software is compatible with Solaris 2.5.1+ or higher.

    Operation:
    PCI bus Interface
    Features
  • PCI Local Bus version 2.1
  • Supports both 32 bit and 64 bit cPCI bus
  • PCI clock rate 25 - 33Mhz
  • Multiple bus masters and DMA capability
  • Programmable burst size 32/64 bytes burst

    •      		Solflower PCI-VMEbus Adapter can be used in two modes - plug-and-play under Solaris 2.5 - 2.6 or using ioctl and mmap() functions to access VME slave memory space. The Solflower nexus driver for the plug-and-play mode allows existing Sun4 VME drivers to run on Sun Ultra PCI-based workstation without modification.
