Overview

The VMIC VMIVME-5576 is a high-performance VMEbus Reflective Memory (RM) module that enables ultra-fast, deterministic data exchange between multiple nodes. Data written to one module is instantaneously propagated to all other nodes over fiber optic links, bypassing operating system and network stack delays. This makes it ideal for real-time control, simulation, and distributed processing in industrial, defense, and scientific applications.

Technical Data

Typical Applications

• Real-time flight simulators and training systems

• High-speed data acquisition and signal processing in physics or defense projects

• Industrial distributed control systems and SCADA networks

• Applications requiring synchronized, deterministic data across multiple computing nodes

FAQ

Q1: How does Reflective Memory work?
A1: When a write occurs on the VMIVME-5576, the hardware automatically broadcasts the data over fiber to all other RM modules, updating their memory within microseconds. This is transparent to software.

Q2: Why use fiber optic links?
A2: Fiber provides high bandwidth, galvanic isolation, and reliable long-distance connectivity (up to ~10 km), essential for synchronized real-time systems.

Q3: Why is RM better than Ethernet for real-time control?
A3: RM operates at the hardware level with microsecond-level deterministic latency, unlike Ethernet, which has variable delays due to software protocol stacks. This ensures precise timing for closed-loop control.
