GE VMIVME-5565-110000 Reflective memory node card
Working principle
Data storage and broadcasting: Each VMIVME-5565-110000 board can be equipped with 64Mbyte or 128Mbyte on-board SDRAM. When data is written to the local SDRAM of a certain node, the data will be automatically broadcast to all other nodes on the network through the high-speed optical fiber data path. The data written into the memory of one node will be simultaneously written into the memory of all nodes in the network, thereby achieving real-time data sharing.
Data packet transmission: Supports dynamic data packet size, ranging from 4 to 64 bytes. The network transmission rate varies depending on the size of the data packet. A 4-byte data packet can reach up to 47.1MB/s, and a 64-byte data packet can reach up to 174MB/s. The serial connection speed can reach up to 2.12Gbaud, ensuring high-speed data transmission.
Data buffering: The board is equipped with a send and receive FIFO (First-in-First-Out buffer). During peak data rate periods, FIFO is used to buffer data to optimize processor and bus performance, maintain high data throughput, and prevent data loss or transmission congestion.
Interrupt transmission: Support any node to generate interrupts. When a specific event occurs at a certain node or requires responses from other nodes, an interrupt signal can be generated to synchronize system processes or track data, facilitating collaborative work and real-time control among multiple nodes.
VME bus connection: It connects and communicates with other devices in the system through the VME bus interface, following the VME bus standard, and can achieve data interaction and collaborative work with other boards or systems under the VME bus architecture.
Hardware platform support: Centered on an innovative and efficiently designed hardware platform, it features high immunity, optional node bypassing, and no additional complex software overhead. Users only need to perform read and write operations on the on-board memory. The rest of the work, such as data broadcasting and transmission control, is automatically completed by the reflection memory node controller.
Application scenarios
Industrial process control: In industrial automated production lines, it is necessary to collect data from multiple sensors in real time, such as temperature, pressure, position, etc., and simultaneously send control instructions quickly to each actuator. The VMIVME-5565-110000 can achieve high-speed sharing of sensor data and control instructions among different controllers and devices, ensuring the coordinated operation of all links and improving production efficiency and product quality.
Simulation and training: In simulation systems such as flight simulators and ship simulators, it is necessary to share the simulation data and status information of multiple subsystems in real time, such as the attitude, speed, and engine status of the aircraft. Through this reflective memory node card, data synchronization among various simulation modules can be guaranteed, providing a realistic simulation environment for trainers and also being used for system testing.
Data acquisition system: In some large-scale data acquisition projects, such as scientific research experiment data acquisition and geological monitoring data acquisition, multiple acquisition devices work simultaneously, generating a large amount of data. The VMIVME-5565-110000 can share the data of each acquisition device to the data processing center in real time, facilitating real-time analysis and processing, and promptly discovering anomalies and patterns in the data.
In the military field, in military command and control systems, it is necessary to rapidly transmit and share key information such as battlefield intelligence and the status of weapon systems to achieve efficient coordination among various combat units. Its high-speed and low-latency data transmission characteristics can meet the strict requirements of military applications for real-time performance and reliability, ensuring that combat instructions can be conveyed and executed promptly and accurately.
Telecommunication communication: At the core switching nodes or data centers of telecommunication networks, a large number of data packets need to be processed and transmitted. The VMIVME-5565-110000 can be used to connect different communication devices and processing modules, achieving high-speed data sharing and exchange, and ensuring the smoothness and stability of network communication.
