VMIC Reflective Memory Network

VMIC reflective memory network is a real-time shared memory system based on high-speed fiber optic networks, specifically designed for applications requiring low latency and high determinism. The following are its core features and advantages:

1. Core Features

• High-Speed Transmission: Utilizes fiber optic communication with transmission rates up to 2.125 Gbps and latency as low as hundreds of nanoseconds.
• Data Sharing: Each node is connected via fiber optics to form a ring network. Data written to local memory is automatically synchronized across all nodes, enabling multi-point updates.
• Hardware Automatic Synchronization: Data transmission is handled by hardware without software intervention, reducing CPU load.
• Cross-Platform Compatibility: Supports various bus architectures (e.g., PCI, VME, CPCI) and operating systems (Windows, Linux, VxWorks, etc.).

2. Application Scenarios

• Real-Time Simulation: Widely used in hardware-in-the-loop simulation systems, such as aerospace and rail transportation.
• Industrial Control: Applied in industrial automation systems requiring high determinism and low latency.
• Distributed Computing: Supports high-speed data sharing among multi-computer systems, suitable for distributed simulation and testing.

3. Technical Advantages

• Deterministic Latency: Data transmission latency is strictly controllable, making it ideal for systems with high real-time requirements.
• High Reliability: Supports redundant transmission and error detection functions to ensure data integrity.
• Strong Scalability: Supports up to 256 nodes, enabling large-scale networking.

4. Typical Products

• PCI-5565: A PCI interface-based reflective memory card with 128 MB memory, suitable for various application scenarios.
• PMC-5565: A PMC interface reflective memory card supporting multi-mode and single-mode fiber optics, with transmission distances up to 10 kilometers.

5. Networking Methods

• Ring Network Mode: Multiple nodes are connected in a ring via fiber optics, with data circulating among nodes.
• Star Mode: Multiple nodes are connected through a HUB, supporting fault node isolation and network reconfiguration.

With its high speed, low latency, and high determinism, VMIC reflective memory network is an ideal choice for real-time systems and distributed simulation fields.
