Description
The GE VMIVME-7750 is a Pentium III processor-based VMEbus single-board computer (SBC) originally engineered by VMIC and later carried under the GE Fanuc / GE Intelligent Platforms embedded-computing portfolio, packaged as a standard 6U single-slot Eurocard for VME64 and VME64x backplanes. It brings desktop-class x86 computing — Intel Pentium III up to 1.26 GHz, Intel 815E chipset, 133 MHz front-side bus, and 512 KB advanced transfer cache — into the deterministic, long-lifecycle VME worldartisantg.com+1.
Because CPU, memory, graphics, dual Ethernet, dual serial, USB, IDE/CompactFlash storage, and a PMC mezzanine site all live on one board, the VMIVME-7750 replaces what would otherwise be a stack of separate controller cards, making it a favourite processor for automated test equipment, aerospace ground benches, process-control VME racks, and legacy defence systems that cannot justify a full platform migrationcxabb.com+1.
Application Scenarios
Consider a defence test agency operating a radar-signature measurement bench built on a 21-slot 6U VME crate: the rack carries waveform-capture I/O, synthetic-instrument modules, and custom signal-conditioning boards that have been in service for nearly two decades, and every module speaks VME. The test sequencer that once ran on an older PowerPC VME CPU has been sunset by its OEM, and rewriting the acquisition chain for a new architecture would cost more than replacing the processor itself. This is the classic problem the GE VMIVME-7750 was built to solve: drop it into the slot-1 position of the existing crate, configure its Universe II-B PCI-to-VME bridge as system controller, boot the existing VxWorks or Linux application from CompactFlash, and the original VME I/O fleet comes alive again on a modern x86 platform. Integration teams no longer need to re-qualify the I/O layer, and the bench keeps its deterministic VME access through the four 32-bit mailboxes and the programmable interrupt handler that map VME IRQs directly into PCI INTA# or SERR# on the VMIVME-7750cxabb.com+1.
