Core Features
Deterministic low latency: Fiber optic synchronous transmission, microsecond level delay, no software protocol overhead, suitable for strict timing requirements of real-time control and simulation.
Transparent data sharing: Node writes are automatically synchronized to the entire network, software is unaware, simplifying distributed system development and improving data consistency.
High reliability design: Supports redundant fiber optic links, built-in ECC error correction, industrial grade wide temperature range, anti vibration/electromagnetic interference, suitable for harsh scenarios such as power and military.
Flexible expansion and compatibility: compatible with VME64x bus, adaptable to new and old VME chassis, supports multiple system platforms, and adapts to existing hardware and software environments.
Dual DMA channels: Independent DMA is used for local and reflective memory data transfer, reducing CPU load and improving data transfer efficiency.
Application scenarios
Real time simulation system: Cross node model data synchronization, such as power grid simulation and flight simulator.
Industrial distributed control: collaborative power generation/transmission equipment, robot cluster control, ensuring data consistency across multiple nodes.
Aerospace/Military: Airborne/shipborne VME system data sharing, high reliability redundancy design suitable for harsh environments.
Data collection and monitoring: Multi node data integration, real-time storage and analysis of high-speed collection system.
