Curtiss-Wright / Synergy Microsystems VCMD Single Processor VME/VME64 Single Board Computer

The Curtiss-Wright/Synergy Microsystems VCMD is a single processor VME/VME64 Single Board Computer built on the PowerPC G4 (7410) architecture for industrial, embedded, and mission-critical applications requiring real-time control and data acquisition. Operating at 400–450 MHz with a 100 MHz memory bus and 2 MB L2 cache per CPU, the VCMD delivers sustained processing performance in space-constrained VME backplane systems. It integrates up to 512 MB on-board SDRAM and 64 MB user flash, with two PMC sites for mezzanine card expansion—optionally extended to five PMC sites via a PEX3 carrier card. The board supports both VxWorks and Linux, enabling flexible software deployment across defense, aerospace, and industrial embedded platforms.

## Technical Specifications

## Key Features

• High-speed 100 MHz memory controller for sustained I/O throughput
• Dual PMC mezzanine interfaces for custom I/O and peripheral integration
• Programmable VME slave functionality across two independent address spaces
• Support for VME64 multi-master and multi-processor configurations
• VxWorks and Linux operating system compatibility

## Typical Applications

• Real-time control systems in airborne and ground-based platforms
• Data acquisition and sensor processing for embedded systems
• Mission-critical industrial controllers requiring VME backplane integration

## Compatibility & Integration

The VCMD integrates directly into VME and VME64 backplane systems. PMC mezzanine slots accommodate standard industry I/O modules, enabling modular system design without redesign of the core processor board. Operating system support for VxWorks and Linux simplifies application porting and reduces development risk across embedded platforms.
