Key Features & Advantages
The **GE VMIVME-7740-740-G** combines military-grade ruggedness with high-performance computing, featuring radiation-tolerant components that maintain functionality in 50krad TID environments. Its deterministic VMEbus architecture ensures <1 µs interrupt latency for real-time critical applications. The integrated dual Gigabit Ethernet ports support IEEE 1588 Precision Time Protocol synchronization across distributed systems.
Unique memory protection: Hardware-based ECC detects and corrects single-bit errors while logging multi-bit errors through system diagnostics. The conduction-cooled design eliminates need for airflow, enabling deployment in sealed enclosures. Onboard watchdog timer automatically reboots the system within 200ms of software lockup, ensuring 99.999% operational availability.

Applications
The **GE VMIVME-7740-740-G** is deployed in airborne radar signal processing systems, handling 2.5 GFLOPs sustained computation while withstanding 15g vibration profiles. Nuclear power plants utilize its radiation-hardened design for reactor monitoring systems that process 500+ analog sensor inputs simultaneously. Military ground vehicles integrate this SBC for vehicle management computers surviving 50g ballistic shocks.
In satellite communication systems, the board’s -40°C cold-start capability ensures reliable operation in polar orbit conditions. Oil & gas exploration equipment leverages its conduction cooling for downhole monitoring at 85°C ambient temperatures. Railway signaling systems benefit from the deterministic Ethernet timing, synchronizing crossing gates within ±500ns across 10km networks.
