Main Features and Advantages
X86-Class Computing in a Rugged VME Form Factor
The defining advantage of the GE VMIVME-77501 is its ability to deliver mature Intel Pentium III x86 computing performance—up to 1.26 GHz with 512 KB of L2 cache—inside a standard 6U VME slot. This means engineers can leverage the entire x86 software ecosystem, from real-time operating systems like VxWorks and QNX to general-purpose stacks like Embedded Linux and Windows NT. The GE VMIVME-77501 effectively eliminates the software-portability gap that traditionally separated commercial off-the-shelf (COTS) PCs from ruggedized industrial controllers.
Transparent PCI-to-VME Bridging for Multi-CPU Architectures
Unlike simpler VME processors that act merely as bus masters, the GE VMIVME-77501 incorporates a transparent PCI-to-VME bridge that allows it to function as a system controller or as a peripheral CPU in multi-processor VME chassis. This capability enables the GE VMIVME-77501 to coordinate seamlessly with data-acquisition boards, communication cards, and I/O modules across the VME backplane, delivering sustained data-transfer rates suitable for high-speed signal processing and closed-loop control.
Rich, Plant-Ready Connectivity
The GE VMIVME-77501 ships with dual 10/100BaseTX Ethernet ports for redundant network topologies, two RS-232 serial ports for legacy device integration, USB ports for peripherals, and a front-panel VGA output driven by its 4 MB AGP SVGA controller. Combined with the on-board PMC expansion slot, the can be tailored to virtually any industrial protocol or interface requirement—whether that means adding a Profibus slave card, a Fibre Channel adapter, a 1553B interface, or a high-speed DSP mezzanine. This flexibility future-proofs the against evolving communication standards.
