DescriptionVMIC VMIPCI-5576 PCI Fiber-Optic Reflective Memory with Interrupts | PCI bus | 175 Mega Baud Reflective Memory
OverviewThe Reflective Memory concept provides a very fast and efficient way of sharing data across distributed computer systems.VMIC’s VMIPCI-5576 Reflective Memory interface allows data to be shared between up to 256 independent systems (nodes) at rates up to 6.2 Mbyte/s. Each Reflective Memory board may be configured with 256 Kbyte to 1 Mbyte of on-board SRAM. The local SRAM provides fast Read access times to stored data. Writes are stored in local SRAM 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 CPU 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. Three separate, user-definable interrupts 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.
IntroductionThe VMIPCI-5576 is a PCI bus board which may be used with other VMIC 5576 family boards to form a high-performance, daisy-chained, fiber-optic network. Data is transferred by writing to on-board global RAM. The data is automatically sent to the same location in memory on all Reflective Memory boards on the network. The Reflective Memory network can include PCI, VME, and Multibus systems. The network-compatible members of the 5576 family include the VMIVME-5576 and VMIMB1-5576.
Key FeaturesHigh-speed, easy-to-use fiber-optic network (170 Mbaud serially) Data written to memory in one node is also written to memory in all nodes on the network Up to 2,000 m between nodes and up to 256 nodes Data transferred at 6.2 Mbyte/s without redundant transfer Data transferred at 3.2 Mbyte/s with redundant transfer 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 transmission mode for suppressing errors No processor overhead No processor involvement in the operation of the network Up to 1 Mbyte of Reflective Memory D32:D16:D8 memory access Single PCI 5 V slot, standard long card PCI target data bursts supported with 44 Mbyte/s transfer rates PCI master DMA controller. DMA transfer rates of 132 Mbyte/s maximum and 33 Mbyte/s sustained. Configurable endian conversions for multiple CPU architectures on the network Communication link compatible with VMIVME-5576 and VMIMB1-5576 Software-addressable digital output bit available at output connector for use with optical switch board or any user-defined purpose Windows NT® OS driver available which operates the VMIPCI-5576 as a network interface board. Allows TCP/IP and other protocol connectivity on a network of VMIPCI-5576 or VMIVME-5576 nodes.
