GE Fanuc VMIVME 5588 High-Speed Reflective Memory Board – VMEbus
The GE Fanuc VMIVME 5588 is a state-of-the-art high-speed reflective memory board designed for VMEbus-based systems requiring ultra-fast, deterministic data sharing across multiple distributed nodes. This board leverages advanced fiber-optic technology to provide a low-latency, high-bandwidth communication channel, with built-in interrupt support for event-driven synchronization. It is ideal for real-time control, simulation, and data acquisition applications where data consistency and timing are critical.
Reflective memory technology enables a shared memory space among up to 256 nodes, where any write performed on one node is automatically reflected to all other nodes within microseconds. The VMIVME 5588 enhances this with high data rates, advanced error correction, and programmable interrupt generation, ensuring reliable and responsive data exchange even in electrically noisy environments.
