反射内存节点卡（RMN Reflective Memory Network）是一种高速的实时网络，VMIVME-5565-110000332-015565-110000-P–VME-5565允许采用不同的总线结构和不同的操作系统的计算机以确定的速率分享实时数据。这种网络的主要特点是其严格的传输确定性和可预测性，以及高速、主机负载轻、软硬兼容性强、易于使用、可靠的传输纠错能力和支持中断信号传输等。

反射内存节点卡是一种PCI设备，提供给用户128MB的读写空间。当网络中的一个节点有写入操作时，这个操作会自动通过光纤链路将数据同步到所有其他节点。这一系列的传输写入操作是由硬件完成的，因此两个节点间的更新延时可以达到100ns级。此外，该节点卡支持光纤传输，节点与节点之间的传输时间通常为1微秒，对于拥有30个节点的系统，通过网络传输到所有节点的时间只需30微秒，而且节点之间的距离可以达到10公里。

在硬件层面，VMIVME-5565-110000332-015565-110000-P–VME-5565反射内存节点卡的工作流程是：当数据需要写入时，数据首先被写入到SDRAM中，同时数据、地址和控制数据会被打包发送到发送FIFO。在这个过程中，SERDES会在接收到FIFO数据的中断后，立即将FIFO的数据读取并转换为串行数据，然后通过光纤收发器发送出去。这个过程的FIFO读取时间只需要大约4个周期。

总的来说，VMIVME-5565-110000332-015565-110000-P–VME-5565反射内存节点卡是一种高性能、高可靠性的实时数据传输设备，适用于需要高速、确定性和可靠性的各种应用场景，如工业自动化、能源管理、医疗设备等领域。

RMN Reflective Memory Network (RMN Reflective Memory Network) is a high-speed real-time network. VMIVME-5565-11000033 2-015565-11010000-p -VME-5565 allows computers with different bus structures and different operating systems to share real-time data at a determined rate. The main characteristics of this network are its strict transmission certainty and predictability, as well as high speed, light host load, strong soft and hard compatibility, easy to use, reliable transmission error correction ability and support for interrupt signal transmission.

The reflected memory node card is a PCI device that provides the user with 128MB of read and write space. When a node in the network has a write operation, this operation automatically synchronizes data to all other nodes through the fiber link. This series of transmission write operations is done by the hardware, so the update delay between the two nodes can reach 100ns. In addition, the node card supports fiber optic transmission, the transfer time between nodes is usually 1 microsecond, for a system with 30 nodes, the time to transfer through the network to all nodes is only 30 microseconds, and the distance between nodes can reach 10 kilometers.

At the hardware level, VMIVME-5565-11000033 2-015565-11010000-p — The working process of the VME-5565 reflected memory node card is that when data needs to be written, the data is first written to SDRAM and at the same time the data, address and control data are packaged and sent to the sending FIFO. In this process, the SERDES will immediately read and convert the FIFO data into serial data after receiving the interruption of the FIFO data, and then send it out through the optical fiber transceiver. The FIFO read time for this process only takes about 4 cycles.

In general, the VMIVME-5565-11000033 2-015565-11010000-P — The VME-5565 Reflective memory node card is a high performance and high reliability real-time data transmission device suitable for a variety of application scenarios that require high speed, certainty and reliability. Such as industrial automation, energy management, medical equipment and other fields.
