Description
MVME7100: Product Overview
The EMERSON MVME7100 is a high-performance Single Board Computer (SBC) designed for VMEbus-based embedded computing systems. Originally developed by Motorola (and later produced by Emerson Network Power), this board serves as the central processing unit in demanding applications requiring reliable operation under harsh environmental conditions. It is built around a PowerPC processor (such as the MPC74xx or similar G4 series) and provides a complete computing subsystem on a single 6U VME card.
The board operates as the main controller in a VME chassis, executing real-time operating systems (RTOS) or embedded Linux to run complex control algorithms, data acquisition, and communication tasks. Its primary function is to provide high computational power while interfacing with other VME boards for I/O, networking, and specialized processing via the high-speed VME64x backplane. The design incorporates ruggedized components and construction techniques to withstand shock, vibration, and extended temperature ranges, making it suitable for deployment in mobile, industrial, and military environments where commercial-grade computers would fail.

Core Features & Customer Value
The board’s primary value is its high performance and ruggedness. The PowerPC processor with AltiVec technology provides substantial computational power for signal processing and complex control algorithms. For system integrators, this means the ability to handle demanding tasks in a compact, reliable form factor. The ruggedized design, including soldered memory and extended temperature components, ensures long-term reliability in environments with extreme temperatures, shock, and vibration, which is critical for military, aerospace, and industrial applications.
The VMEbus architecture provides a proven, deterministic platform for critical systems. The availability of PMC expansion sites offers significant flexibility, allowing customization with additional I/O, communication, or specialized processing cards without redesigning the entire board. This modularity protects investments and allows systems to be tailored to specific mission requirements. For engineers, this combination of performance, reliability, and expansion capability reduces development risk and time-to-market for complex embedded systems.
In defense systems, the MVME7100 is used in radar signal processing, electronic warfare (EW) systems, and military vehicle computing platforms where reliability and performance under harsh conditions are paramount.
In industrial automation, it serves as the main controller in high-speed manufacturing equipment and test stands requiring real-time deterministic performance.
