Description

The GE VMIVME-7807 is a high-performance,32-bit VMEbus-compatible single-board computer(SBC)based on the Intel Pentium®M processor architecture,designed for embedded control,data acquisition,and real-time computing in demanding industrial,military,aerospace,and power generation applications.Manufactured by GE Intelligent Platforms(formerly VMIC),it integrates robust processing power with extensive I/O connectivity within the rugged VME64x form factor—making it ideal for legacy system sustainment and modernization of mission-critical platforms.

With support for real-time operating systems(RTOS)like VxWorks,Linux,and Windows Embedded,the VMIVME-7807 serves as a powerful controller or data concentrator in distributed systems such as turbine governors,radar signal processors,substation automation,and test&simulation rigs.

Application Scenarios

At a U.S.Navy Aegis-class destroyer undergoing combat system upgrades,the aging VME-based fire-control processor suffered from obsolescence and thermal instability.The engineering team selected the GE VMIVME-7807 as a drop-in replacement due to its pin-compatible VME64x interface,extended temperature operation,and 1.6 GHz Pentium M performance—delivering a 5×speed increase over the legacy board.Crucially,its conformal coating and MIL-STD-810G-compliant design withstood shock,vibration,and salt fog during sea trials.The system achieved full operational readiness without rewriting existing VxWorks application code—proving that the VMIVME-7807 isn’t just a CPU—it’s a lifecycle extender for billion-dollar platforms.

Technical Principles and Innovative Values

Innovation Point 1:Legacy-to-Modern Bridge Without Re-Architecture

The VMIVME-7807 maintains strict VME mechanical and electrical compatibility while introducing gigabit Ethernet,SATA,and USB—enabling legacy VME systems to integrate with modern networks and storage without redesigning backplanes or software drivers.

Innovation Point 2:Real-Time Performance with Low Power&Heat

Unlike desktop-derived SBCs,the Pentium M in the VMIVME-7807 delivers high IPC(instructions per cycle)with minimal thermal output—critical for conduction-cooled or sealed enclosures where active cooling is impossible.

Innovation Point 3:PMC Expansion for Custom I/O

The integrated PMC site allows users to add FPGA-based I/O,ARINC 429,MIL-STD-1553,or high-speed ADC/DAC without consuming additional VME slots—maximizing functionality in space-constrained chassis.

Application Cases and Industry Value

Nuclear Power Plant Safety System(France):

A reactor protection system required CPU upgrade without requalification.The VMIVME-7807’s binary compatibility with prior VxWorks builds allowed seamless insertion,extending system life by 15+years under ASN regulatory approval.

Wind Tunnel Data Acquisition(NASA):

Used as a real-time data aggregator for 500+strain gauges and pressure sensors,the VMIVME-7807 processed and timestamped data at 10 kHz per channel—leveraging its deterministic interrupt latency(<5µs).

Ensure VME slot supports 3.3 V signaling(backward compatible with 5 V).

Use proper grounding straps—VME systems are sensitive to ESD.

Configure boot device(CF,HDD,or network)via onboard DIP switches or BIOS.

Enable write-protect on OS drive in field deployments to prevent corruption.

Maintenance Guidance:

Monitor CPU temperature via IPMI or BIOS health logs.

Replace electrolytic capacitors after 10 years in high-temp environments.

Keep spare units with identical BIOS and MAC address backups.
