GE VMIVME-7805 Single Board  Computer

DESCRIPTION

The VMIVME-7805 brings the Intel Pentium 4  Processor - M to VME, offering processor speeds up to 2.2 GHz.  The Intel Pentium 4 Processor - M is the first Intel mobile  processor with the Intel NetBurst™ microarchitecture. The Intel  Pentium 4 Processor - M utilizes a 478-pin, Micro Flip-Chip Pin  Grid Array (Micro-FCPGA) package, and plugs into a surfacemount, Zero Insertion Force (ZIF) socket. The Intel Pentium 4  Processor - M maintains full compatibility with IA32 software.

The Intel NetBurst microarchitecture features include hyperpipelined technology, a rapid execution engine, a 400 MHz  system bus, and an execution trace cache. The hyper-pipelined  technology doubles the pipeline depth in the Intel Pentium 4  Processor - M allowing the processor to reach much higher core  frequencies. The rapid execution engine allows the two integer  ALUs in the processor to run at twice the core frequency, which  allows many integer instructions to execute in 1/2 clock tick. The  400 MHz system bus is a quad-pumped bus running off a  100 MHz system clock, making 3.2 Gbyte/s data transfer rates  possible. The execution trace cache is a first level cache that stores approximately 12 Kbyte decoded micro-operations,  which removes the instruction decoding logic from the main  execution path, thereby increasing performance.

Digital Visual Interface (DVI):

The VMIVME-7805 has a digital  visual interface that provides a high speed digital connection for  visual data types that are display technology independent. DVI  is a display interface developed in response to the proliferation  of digital flat-panel displays. For the most part, these displays  are currently connected to an analog video graphics array (VGA)  interface and, thus, require a double conversion. The digital  signal from the computer must be converted to an analog signal  for the analog VGA interface, then converted back to a digital  signal for processing by the flat-panel display. This inherently  inefficient process takes a toll on performance and video quality  and adds cost. In contrast, when a flat-panel display is  connected to a digital interface, no digital-to-analog conversion  is required.

DVI Connectors:

The digital DVI connector has 24 pins that can  accommodate up to two TMDS links and the VESA DDC and  EDID services. The DVI specification defines two types of  connectors:

• DVI-Digital (DVI-D) supports digital displays only (not  supported)  

• DVI-Integrated (DVI-I) supports digital displays and is  backward compatible with analog displays (used on the  VMIVME-7805)

Ethernet Controller:

The VMIVME-7805 supports Ethernet LANs  with two Intel Ethernet controllers (one 82540EM Gigabit  Ethernet controller and the other internal to Intel’s chipset  ICH4-M). 10BaseT, 100BaseTX and Gigabit Ethernet options are  supported via one RJ45 connector. 10BaseT and 100BaseTX are  supported via a second RJ45 connector. Remote LAN booting is  supported.

Remote Ethernet Booting:

The VMIVME-7805 utilizes a ROM  BIOS that provides the ability to remotely boot the  VMIVME-7805 using NetWare, TCP/IP or RPL network protocols.  

Remote Ethernet Features:

• NetWare, TCP/IP, RPL network protocol support  

• Unparalleled boot sector virus protection  

• Detailed boot configuration screens  

• Comprehensive diagnostics  

• Optional disabling of local boots  

• Dual-boot option lets users select network or local booting

Flash Memory:

The VMIVME-7805 provides up to 1 Gbyte of IDE  CompactFlash memory accessible through the secondary IDE  port. The VMIVME-7805 BIOS includes an option to allow the  board to boot from the Flash memory.

Watchdog Timer:

The VMIVME-7805 provides a software-programmable watchdog timer. The watchdog timer is enabled  under software control. Once the watchdog timer is enabled,  software must access the timer within the specified timer period  or a timeout will occur. A user configurable jumper allows the  timeout to cause a reset. Independent of the jumper, software  can enable the watchdog timer to cause a nonmaskable  interrupt (NMI) or a VMEbus SYSFAIL.

IDE Interface:

The IDE interface on the VMIVME-7805 supports  ATA-33, ATA-66 and ATA-100 drives and automatically  determines the proper operating mode based on the type of  drive used. In order to properly function in the ATA-100 mode, a  special 80 conductor cable must be used instead of the  standard 40 conductor cable. This cable is typically available  from the ATA-100 drive manufacturer.
