Description 1786370374VMIC VMIPCI-5565 PCI Ultrahigh Speed Fiber-Optic Reflective Memory with Interrupts, PCI bus, 2 Giga Baud Reflective Memory.The Reflective Memory concept provides a very fast and efficient way of sharing data across distributed computer systems.The VMIPCI-5565 Reflective Memory interface allows data to be shared between up to 256 independent systems (nodes) at rates up to 174MB/s. Each Reflective Memory board may be configured with 64MB or 128MB of onboard SDRAM. The local SDRAM provides fast Read access times to stored data. Writes are stored in local SDRAM and broadcast over a high speed fiberoptic 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 the host computer and bus performance to maintain high data throughput.The Reflective Memory also allows interrupts to one or more nodes by writing to a byte register. These interrupt (four levels, each user definable) signals may be used to synchronize a system process, or used to follow any data. The interrupt always follows the data to ensure the reception of the data before the interrupt is acknowledged.Each node on the system has a unique identification number between 0 and 255. The node number is established during hardware system integration by placement of jumpers on the board. This node number can be read by software by accessing an onboard register. In some applications, this node number would be useful in establishing the function of the node.
Key FeaturesHigh 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 300m, single mode fiber up to 10km Dynamic packet size, 4 to 64 bytes of data Transfer rate 47.1MB/s (4 byte packets) to 174MB/s (64 byte packets) 64MB or 128MB 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 Redundant transfer mode for extra error suppression No processor overhead No processor involvement in the operation of the network PCI 64-bit 66MHz transfers PCI revision 2.2 compliant VMISFT-RFM2g* network and shared memory driver included Operating system/driver support for Windows NT®, Windows® 2000, VxWorks®, and Linux®
