VMIC VMIPCI 5588-101 High Speed Fiber Optic Reflective Memory Board

The VMIC VMIPCI 5588-101 is a high-performance fiber optic reflective memory board designed for PCI-based systems. This board enables high-speed, deterministic data sharing between multiple distributed nodes, with automatic memory replication across all connected nodes. Its fiber optic interface provides complete electrical isolation, noise immunity, and support for long-distance communication, making it ideal for simulation, distributed control, and data acquisition applications.

Reflective memory technology allows any write to the local memory to be automatically propagated to all other nodes in the network with extremely low latency, eliminating the need for complex software communication protocols and offloading the host CPU.

Key Features

• Reflective Memory Architecture: Automatic data replication across all network nodes.

• Fiber Optic Interface: Provides EMI/RFI immunity and long-distance communication.

• High Speed: Supports data rates up to 2.5 Gbps over fiber-optic links.

• Low Latency: Sub-microsecond propagation delay for real-time synchronization.

• PCI Bus Compatibility: Standard PCI form factor for easy system integration.

• Scalable Network: Supports up to 256 nodes in multi-drop or daisy-chain topology.

• Diagnostic Features: Built-in error detection and network status monitoring.

Technical Specifications

The VMIPCI 5588-101 features onboard reflective memory, typically ranging from 128 MB to 512 MB. Data transfers are performed using hardware DMA engines that offload the host CPU. The fiber optic interface supports multi-mode or single-mode fiber, providing distances up to several kilometers.

The board conforms to standard PCI mechanical and electrical specifications, with a 32-bit/33 MHz or 64-bit/66 MHz PCI interface. Power is derived from the PCI bus, with typical consumption of 5-10W.

Applications

• Distributed Simulation: Flight simulators, power grid simulators, and vehicle dynamics simulation.

• Distributed Control: Synchronizing multiple controllers in industrial plants and power generation.

• Data Acquisition: Merging data from multiple acquisition systems into a common repository.

• Test and Measurement: Coordinating distributed test instruments.

• Radar and Sonar Processing: Sharing processed data across multiple processing boards.

Integration and Configuration

Installing the VMIPCI 5588-101 is straightforward: the board plugs into any standard PCI slot. Each node is assigned a unique ID, and the network topology is configured via software. Once initialized, memory writes are automatically replicated to all nodes.

Drivers for VxWorks, Linux, and Windows are available, with a comprehensive API for application development. The board includes diagnostic software for network monitoring and fault detection.

Benefits

• Real-Time Performance: Deterministic, low-latency data sharing eliminates communication bottlenecks.

• Reduced CPU Load: Automatic data replication offloads the host processor.
