Description
The GE VMIVME - 7750 - 746001 350 - 027750 - 746001 K is a single-board computer based on the VMEbus. Processor Performance: It adopts an Intel Pentium III processor, which can provide a processor speed of up to 1.26GHz, with 32-bit addressing and a 64-bit data bus. Its superscalar architecture allows three instructions to be executed per clock cycle. It also has a dynamic branch prediction unit, separate instruction and data caches, and MMX™ technology, all of which contribute to improving the processor's performance. It is equipped with 256KB (512KB for 1.26GHz) of Advanced Transfer Cache (on-die, full-speed Level 2 cache). Using a dual independent bus architecture, it can achieve high bandwidth, and this secondary cache runs at the same clock frequency as the processor.
Memory and Storage:
It supports up to 512MB of PC133 SDRAM, using a single SODIMM.
It provides up to 1GB of IDE CompactFlash memory, which can be accessed through an auxiliary ID, and the BIOS supports booting from the flash memory.
Communication Interfaces:
It supports Ethernet LAN and is equipped with two Intel Ethernet controllers (one 82559 and the other inside the Intel chipset ICH2), enabling high-speed network communication.
There are two 16550-compatible serial ports on the front panel. The serial channels have a 16 - bFIFO and support a baud rate of up to 115Kbaud, which can be used for serial communication with other devices.
VMEbus-related Functions:
VMEbus Requester: The microprocessor can use any VMEbus request line (BR3* to BR0*) under software control to request and obtain bus control rights, and can be programmed to operate in the following modes: Release on Request (ROR), Release on Completion (RWD), VMEbus Capture and Hold (BCAP).
Mailbox: The VMEbus interface provides four 32-bit mailboxes, which can be accessed by both the microprocessor and the VMEbus for inter-processor communication. When the VMEbus accesses the mailbox, it can interrupt the microprocessor.
Interrupt Handler: The interrupt handler can monitor and be programmed to respond to any or all VMEbus IRQ* lines. All interrupts related to the normal process of the VMEbus can be mapped to PCI INTA# or SERR# interrupts, including mailbox interrupts, VMEbus interrupts, etc.; all interrupts related to the error handling of the VMEbus can also be mapped to PCI INTA# or SERR#, such as ACFAIL* interrupts, BERR* interrupts, etc.
Interrupt Generator: It can issue interrupts on any one or all of the seven VMEbus interrupt lines (IRQ7* to IRQ1*) under software control, and all interrupt lines are associated with a common ID register.
Other Features:
It has an internal AGP SVGA controller and 4MB of display cache, which can provide graphic display functions.
It provides users with two 16-bit timers and two 32-bit timers (in addition to the system timer), and also has a software-programmable watchdog timer.
The system controller provides a SYSCLK driver, an IACK* daisy chain driver, and a VMEbus access timeout timer, and also provides an arbitration timeout function.
It supports a variety of operating systems, such as Windows® XP, Windows® 2000, VxWorks®, Solaris™, QNX®, LynxOS®, and Linux®, etc., which is convenient for users to choose according to specific applications.
Physical Characteristics: The size is approximately 263×58×28mm, the weight is approximately 4.3kg, and it is originally produced in the United States.
The GE VMIVME - 7750 - 746001 350 - 027750 - 746001 K is mainly applied in the field of industrial automation, such as the aluminum industry, automotive industry, aviation industry, metallurgical industry, etc. It can be used for various tasks such as data collection, control, and monitoring, helping enterprises to improve production efficiency, reduce energy consumption, decrease the failure rate, and enhance the overall operation benefits.
