Main Features and Advantages
The GE VMIVME-7750 derives its competitive edge from a carefully balanced architecture that fuses commercial-off-the-shelf (COTS) computing horsepower with military-grade ruggedness. The Pentium® III processor — with its superscalar execution core, MMX instruction set, and 512 KB of on-die L2 cache running at full core frequency — empowers the GE VMIVME-7750 to execute complex floating-point algorithms, signal-processing routines, and multi-threaded RTOS tasks without bottleneck. This computational headroom makes the board ideally suited for applications where a traditional PLC would fall short in throughput.
Passive cooling and mechanical robustness:
The GE VMIVME-7750 employs a pure passive heatsink thermal solution with no moving fan parts, effectively removing the most frequent cause of field failures in embedded computers. Paired with a wide-temperature bill of materials and a PCB design tolerant of 5 g vibration and 50 g shock per MIL-STD-810, the GE VMIVME-7750 sustains uninterrupted operation in turbine enclosures, mobile vehicles, shipboard panels, and airborne equipment where ambient temperatures swing from -40 °C to +85 °C.
Connectivity and network integration:
Two independent 10/100 Mbps Ethernet ports give the GE VMIVME-7750 native support for redundant networking, segregated control-versus-data traffic, or remote boot scenarios. The LanWorks BootWare® firmware enables PXE/BootP/DHCP/RPL network startup, allowing the to run diskless in secure environments. Two RS-232 serial ports, two USB 1.1 ports, a parallel port, and a PS/2 keyboard/mouse combo connector round out the legacy I/O complement.
Expansion flexibility via PMC:
A single IEEE P1386-compliant PMC site transforms the from a general-purpose SBC into a mission-specific computing node. By populating the PMC slot with fiber-optic network cards, MIL-STD-1553B interfaces, Profibus couplers, or high-speed analog acquisition modules, engineers can tailor the to exact project requirements without redesigning the base platform.
System controller capability:
Through the Tundra Universe IIB PCI-to-VME bridge, the can assume the role of VME Slot 1 system controller or yield that role to another board under software control. Four 32-bit mailbox registers facilitate inter-processor communication, while hardware byte-swapping ensures seamless little-endian/big-endian compatibility across heterogeneous VME systems. A software-programmable watchdog timer and 32 KB of battery-backed NVRAM further harden the against software lockups and power interruptions.
