Memory Board offers 64 or 128 Mbyte SDRAM.

Press Release Summary:



VMIPCI-5565 is a 2 Gbaud, fiber-optic, PCI bus-compatible reflective memory board. It allows computers, workstations, PLCs, and other embedded controllers with dissimilar or no operating systems to share data in real-time between up to 256 independent systems at rates up to 174 Mbyte/s. Writes are stored in local SDRAM and broadcast over high-speed fiber-optic data path. Transmit and Receive FIFOs buffer data during peak data rates.

VMIC Announces Addition to Its Ultrahigh-Speed Fiber-Optic Reflective Memory Product Line


Huntsville, AL (January 11, 2002). VMIC introduces the newest member of its Reflective Memory product line, VMIPCI-5565. The VMIPCI-5565 is a 2 Gbaud, fiber-optic, PCI bus-compatible Reflective Memory board. This product allows computers, workstations, PLCs, and other embedded controllers with dissimilar or no operating systems to share data in real-time
between up to 256 independent systems (nodes) at rates up to 174 Mbyte/s and can be configured with 64 or 128 Mbyte of on-board SDRAM. On-board SDRAM allows the local SDRAM to provide fast Read access times to stored data. Writes are stored in local SDRAM and broadcast over a high-speed fiber-optic data path to other Reflective Memory nodes. The transfer of data between nodes is software transparent so no I/O overhead is required. Transmit and Receive FIFOs buffer data during peak data rates to optimize processor and bus performance, maintaining high data throughput over the network.

Other members of VMIC's ultrahigh-speed Reflective Memory product line include a PCI mezzanine card (VMIPMC-5565) and, coming soon, a VMEbus-compatible board (VMIVME-5565). All of these products are network compatible, and may be integrated into a network in any combination.

VMIPCI-5565 Features:
* High-speed, easy-to-use fiber-optic network (2.12 Gbaud serially)
* Data written to memory in one node is also written to memory in all nodes on the network
* Up to 256 nodes
* Connection with multimode fiber up to 300 m, single-mode fiber up to 10 km
* Dynamic packet size, 4 to 64 bytes of data
* Transfer rate 43 Mbyte/s (4 byte packets) to 174 Mbyte/s (64 byte packets)
* 64 or 128 Mbyte SDRAM Reflective Memory
* Two independent DMA channels
* Any node on the network can generate an interrupt in any other node on the network or in all network nodes with a single command
* Error detection
* No processor overhead
a No processor involvement in the operation of the network
* PCI 64-bit 66 MHz, and backward compatible to 32-bit 33 MHz transfers
* PCI revision 2.2 compliant
* Operating system/driver support includes Windows NT®, Windows(R), VxWorks, and Linux
