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 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.
