反射內(nèi)存節(jié)點(diǎn)卡（RMN Reflective Memory Network）是一種高速的實(shí)時(shí)網(wǎng)絡(luò)，VMIVME-5565-110000332-015565-110000-P–VME-5565允許采用不同的總線結(jié)構(gòu)和不同的操作系統(tǒng)的計(jì)算機(jī)以確定的速率分享實(shí)時(shí)數(shù)據(jù)。這種網(wǎng)絡(luò)的主要特點(diǎn)是其嚴(yán)格的傳輸確定性和可預(yù)測性，以及高速、主機(jī)負(fù)載輕、軟硬兼容性強(qiáng)、易于使用、可靠的傳輸糾錯(cuò)能力和支持中斷信號傳輸?shù)取?/p>

反射內(nèi)存節(jié)點(diǎn)卡是一種PCI設(shè)備，提供給用戶128MB的讀寫空間。當(dāng)網(wǎng)絡(luò)中的一個(gè)節(jié)點(diǎn)有寫入操作時(shí)，這個(gè)操作會自動通過光纖鏈路將數(shù)據(jù)同步到所有其他節(jié)點(diǎn)。這一系列的傳輸寫入操作是由硬件完成的，因此兩個(gè)節(jié)點(diǎn)間的更新延時(shí)可以達(dá)到100ns級。此外，該節(jié)點(diǎn)卡支持光纖傳輸，節(jié)點(diǎn)與節(jié)點(diǎn)之間的傳輸時(shí)間通常為1微秒，對于擁有30個(gè)節(jié)點(diǎn)的系統(tǒng)，通過網(wǎng)絡(luò)傳輸?shù)剿泄?jié)點(diǎn)的時(shí)間只需30微秒，而且節(jié)點(diǎn)之間的距離可以達(dá)到10公里。

在硬件層面，VMIVME-5565-110000332-015565-110000-P–VME-5565反射內(nèi)存節(jié)點(diǎn)卡的工作流程是：當(dāng)數(shù)據(jù)需要寫入時(shí)，數(shù)據(jù)首先被寫入到SDRAM中，同時(shí)數(shù)據(jù)、地址和控制數(shù)據(jù)會被打包發(fā)送到發(fā)送FIFO。在這個(gè)過程中，SERDES會在接收到FIFO數(shù)據(jù)的中斷后，立即將FIFO的數(shù)據(jù)讀取并轉(zhuǎn)換為串行數(shù)據(jù)，然后通過光纖收發(fā)器發(fā)送出去。這個(gè)過程的FIFO讀取時(shí)間只需要大約4個(gè)周期。

總的來說，VMIVME-5565-110000332-015565-110000-P–VME-5565反射內(nèi)存節(jié)點(diǎn)卡是一種高性能、高可靠性的實(shí)時(shí)數(shù)據(jù)傳輸設(shè)備，適用于需要高速、確定性和可靠性的各種應(yīng)用場景，如工業(yè)自動化、能源管理、醫(yī)療設(shè)備等領(lǐng)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.
