Overview
The VMIC VMIVME-5576 is a VMEbus Reflective Memory (RM) module designed for deterministic, real-time data exchange across multiple computer systems. It maintains a physically distributed shared memory space, automatically propagating local writes to all connected nodes via fiber optics, bypassing network and OS delays. This ensures ultra-low-latency communication for tightly synchronized control, simulation, and data acquisition systems.

FAQ
Q1: What does "Reflective Memory" mean for the VMIVME-5576?
A1: Reflective Memory mirrors a portion of local memory across all nodes. Any change on one node is immediately reflected on all connected nodes via fiber, achieving near-instant data consistency.
Q2: Why is the fiber optic connection important?
A2: Fiber ensures galvanic isolation (eliminating noise and ground loops) and allows long-distance, high-speed, low-latency data transfer between nodes.
Q3: How does VMIVME-5576 latency compare to Ethernet?
A3: Standard Ethernet has variable latencies in the hundreds of microseconds to milliseconds. The VMIVME-5576 achieves deterministic latency typically under 1 μs by using a hardware-only data path.
