描述
主要产品详情和功能
反射内存接口：VMIVME-5565的核心功能是实现反射内存（通常称为共享内存或反射内存）。该技术在多个独立计算机系统（节点）之间创建共享数据空间。当数据写入一个节点的反射内存时，会自动快速地“反射”（复制）到所有其他连接节点的反射内存中。
VMEbus兼容性：它是一个VMEbus模块，这意味着它可以直接插入VMEbus背板。VMEbus是一种强大的高性能总线标准，因其多处理能力和可靠性而广泛用于工业控制、航空航天、国防和科学应用。
高速数据交换：反射内存以其极低的延迟和高吞吐量而闻名。这允许在系统之间实现确定性（可预测）和实时数据共享，使其成为对时间要求严格的应用的理想选择。
全局数据一致性：确保所有连接节点都拥有相同的、同步的共享数据副本。这简化了实时应用程序的编程，因为开发人员无需管理复杂的网络协议或同步机制。
容错/冗余：反射内存的本质就支持冗余。如果一个节点发生故障，其他节点仍可继续使用共享数据运行，从而提高系统弹性。
处理器间通信(IPC)：它可作为直接的内存到内存链路，促进多个处理器或控制系统之间的高速通信。
32位P1/P2 VME接口：该模块支持32位VMEbus接口，提供宽阔的数据路径以实现高效传输。

Key Product Details and Functions
Reflection Memory Interface:The core function of the VMIVME-5565 is to implement Reflection Memory(often called Shared Memory or Reflective Memory).This technology creates a shared data space across multiple independent computer systems(nodes).When data is written to the Reflection Memory on one node,it’s automatically and rapidly”reflected”(copied)to the Reflection Memory on all other connected nodes.
VMEbus Compatibility:It’s a VMEbus module,meaning it plugs directly into a VMEbus backplane.The VMEbus is a robust,high-performance bus standard commonly used in industrial control,aerospace,defense,and scientific applications due to its multiprocessing capabilities and reliability.
High-Speed Data Exchange:Reflection Memory is known for its extremely low latency and high throughput.This allows for deterministic(predictable)and real-time data sharing between systems,making it ideal for applications where timing is critical.
Global Data Consistency:It ensures that all connected nodes have an identical,synchronized copy of the shared data.This simplifies programming for real-time applications,as developers don’t need to manage complex network protocols or synchronization mechanisms.
Fault Tolerance/Redundancy:The nature of Reflection Memory inherently supports redundancy.If one node fails,the others continue to operate with the shared data,contributing to system resilience.
Inter-Processor Communication(IPC):It facilitates high-speed communication between multiple processors or control systems,acting as a direct memory-to-memory link.
32-bit P1/P2 VME Interface:The module supports the 32-bit VMEbus interface,providing a wide data path for efficient transfers.
