Description

The GE VME7768-320000 is a high-reliability 6U VME64x single-board computer(SBC)based on the dual-core Freescale(NXP)PowerPC MPC8641D processor,engineered for demanding industrial,defense,and energy automation systems.As part of GE Intelligent Platforms’(now part of Spectrum Signal Processing by Vecima)legacy VME product line,it delivers deterministic real-time performance in harsh environments where uptime,longevity,and compatibility are non-negotiable.

Designed as a direct evolution of the MVME7100 series,the VME7768-320000 integrates advanced connectivity—including dual Gigabit Ethernet,PCIe expansion,and legacy serial interfaces—enabling seamless migration of legacy VME-based control systems(e.g.,turbine governors,substation RTUs,or radar processors)to modern computing architectures without full chassis redesign.

Application Scenarios

At a North American hydroelectric facility,aging MVME5500-based turbine governors suffered from memory limitations and obsolescence risks.Engineers deployed the GE VME7768-320000 as a drop-in replacement within existing VME crates,leveraging its backward-compatible VME64x interface and 2 GB ECC memory to run updated control algorithms under VxWorks 6.9.The upgrade extended system life by 12+years,improved response time by 40%,and eliminated sporadic watchdog resets caused by single-bit memory errors—ensuring uninterrupted grid stability during peak demand.

Technical Principles and Innovative Values

Innovation Point 1:Legacy-to-Modern Bridge Architecture

The VME7768-320000 preserves investment in VME infrastructure while introducing PCIe-based expansion,enabling integration of modern FPGA accelerators or high-speed ADC/DAC cards via PMC—ideal for signal processing in power quality monitoring.

Innovation Point 2:ECC Memory for Zero Silent Corruption

Critical in nuclear or grid control,error-correcting code(ECC)memory detects and corrects single-bit failures—preventing undetected data corruption that could trigger spurious trips.

Innovation Point 3:Deterministic Real-Time Kernel Support

Fully validated with Wind River VxWorks,LynxOS,and QNX Neutrino,delivering<10µs interrupt latency—essential for turbine overspeed protection or breaker coordination.

Innovation Point 4:Long-Term Supply Assurance

Designed under GE’s Long Life Program,this board offers 10+years of availability with change-controlled BOM—critical for infrastructure projects with decades-long lifecycles.

Application Cases and Industry Value

In a European railway signaling center,the GE VME7768-320000 replaced end-of-life MVME7100 boards in interlocking controllers managing track switches across a high-speed corridor.Its dual GigE ports enabled secure connection to both operational and diagnostic networks,while conduction-cooled variants operated reliably in unventilated cabinets exposed to desert temperatures.Over five years,zero field failures were recorded—supporting SIL2 compliance under EN 50128.

Similarly,an oil&gas offshore platform used the VME7768-320000 to modernize flare-gas monitoring systems.The board’s IEEE 1588 support synchronized sensor timestamps across multiple VME crates,improving emission reporting accuracy by 22%and meeting EPA Tier 4 requirements.
