The VME5565-VMIVME-5565-11000-332-015565-110,000-P is a reflective memory node card, a high-speed real-time network that allows computers with different bus structures and operating systems to share real-time data at a defined rate. This kind of network not only has strict transmission certainty and predictability, but also has the characteristics of high speed, light host load, strong soft and hard compatibility, easy to use, reliable transmission error correction ability, support for interrupt signal transmission and so on.

Vme5565-vmivme-5565-11000-332-015565-110,000-p is mainly connected by a reflection memory card through optical fiber and other transmission media. Each computer on the network insert a reflection memory card to form each node. The memory on the reflected memory card of each node has a shared copy of the data of other nodes on the reflected memory network. This node card can be inserted in a variety of bus motherboards, such as PCI, CompactPCI/PXI, VME, etc., each reflection memory card occupies a memory address. When any computer on the network writes data to a local reflection memory card, that data and the corresponding memory address are broadcast to all other reflection memory cards on the network and stored in the same location.

The main functions of VME5565-VMIVME-5565-11000-332-015565-110000-P include:

Data replication: Reflective memory can autonomously copy the memory contents of one processor to the memory nodes of all other network members.

High-speed transmission: The transmission time between nodes is usually in the order of microseconds, for example, for a system with 30 nodes, the transmission time to all nodes through the network is only 30 microseconds.

High data throughput: Supports data sharing between up to 256 independent systems (nodes) at rates of up to 170 Mbyte/s.

Real-time: Data transmission between nodes is independent of the operating system of the local node, so there is no need for I/O overhead, so as to achieve real-time data transmission.

Remote access: The local processor can read this data at any time without having to connect to the network.

Error handling: Each reflective memory board can be configured with on-board SDRAM and provides reliable transmission error correction.

Overall, the VME5565-VMIVME-5565-11000-332-015565-110,000-p is a key component in the reflective memory network, which enables the nodes in the network to share data at high speed and in real time, and provides powerful error handling capabilities. This technology is widely used in areas requiring high performance, high reliability and real-time performance, such as industrial automation, communications, aerospace and so on.
