VMIVME-7750 -ABCDEF
The VMIVME-7750* brings the Intel Pentium
III processor to VME, offering processor speeds up to 1.26
GHz. The Pentium III processor has 32-bit addressing and
a 64-bit data bus. Its superscalar architecture allows three
instructions to be executed per clock cycle. A dynamic branch
prediction unit, separate instruction and data caches, and
MMX™ technology also increase the processor’s performance.
The Pentium III processor also provides 256 Kbyte (1.26
GHz has 512 Kbyte) of advanced transfer cache (on-die, full
speed level 2 cache) using dual independent bus architecture
for high bandwidth and performance. This L2 cache
operates at the same clock frequency as the processor, thus
improving performance.
DRAM Memory: The VMIVME-7750 accepts one 144-pin SDRAM
SODIMM for a maximum memory capacity of 512 Mbyte. The
DRAM is dual ported to the VME.
BIOS: System and video BIOS are provided in reprogrammable
flash memory.
Super VGA Controller: High resolution graphics and multimediaquality
video are supported on the VMIVME-7750 by a built-in 815E
chipset AGP graphics adapter. The adapter is complemented by 4
Mbyte external synchronous DRAM cache with a high-bandwidth
64-bit data interface. Screen resolutions up to 1,600 x 1,200 x 256
colors (single view mode) are supported by the graphics adapter.
Ethernet Controller: The VMIVME-7750 supports Ethernet LANs
with two Intel Ethernet controllers (one 82559 and the other
internal to Intel’s chipset ICH2). 10BaseT and 100BaseTX options
are supported via two RJ45 connectors. Remote LAN booting
is supported.
Remote Ethernet Booting: The VMIVME-7750 utilizes Lanworks
Technologies, Inc.’s BootWare®. BootWare provides the ability to
remotely boot the VMIVME-7750 using NetWare, TCP/IP, or RPL
network protocols.
BootWare 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 bootin
Serial Ports: Two 16550-compatible serial ports are featured on
the VMIVME-7750 front panel. The serial channel has a 16-byte
FIFO to support baud rates up to 115 Kbaud. Requires two micro-
DB9 to standard DB9 adapters, Abaco P/N 360-010050-001.
Keyboard and Mouse Ports: The VMIVME-7750 has a combined
PS/2 keyboard and mouse connector. A Y-adapter cable
is included.
Flash Memory: The VMIVME-7750 provides up to 1 Gbyte of IDE
CompactFlash memory accessible through the secondary IDE
port. The VMIVME-7750 BIOS includes an option to allow the
board to boot from the Flash memory.
Timers: The VMIVME-7750 provides the user with two 16-bit
timers and two 32-bit timers (in addition to system timers).
These timers are mapped in I/O space, and are completely
software programmable.
Watchdog Timer: The VMIVME-7750 provides a softwareprogrammable
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 jumper allows the timeout to cause
a reset. Independent of the jumper, software can enable the
watchdog timeout to cause a nonmaskable interrupt (NMI) or a
VMEbus SYSFAIL.
Nonvolatile SRAM: The VMIVME-7750 provides 32 Kbyte of
nonvolatile SRAM. The contents of the SRAM are preserved when
+5V power is interrupted or removed from the unit.
PMC Expansion Site: The VMIVME-7750 supports IEEE P1386
common mezzanine card specification with a 5V PCI mezzanine
card (PMC) expansion site. The PMC site provides for standard
I/O out the VMEbus front panel. An optional I/O connection to the
VMEbus P2 connection can be provided.
Contact Abaco for more information concerning PMC modules
and compatibility.
Universal Serial Bus (USB): The VMIVME-7750 provides a front
panel dual connection hub host controller for the USB. Supported
USB features include: isochronous data transfers, asynchronous
messaging, self-identification and configuration of peripherals, and
dynamic (hot) attachment.
VMEbus Interface: The VMIVME-7750 VMEbus interface is based
on the Universe IIB high performance PCI-to-VME interface from
Newbridge/Tundra.
System Controller: The VMEbus system controller capabilities
allow the board to operate as a slot 1 controller, or it may be
disabled when another board is acting as the system controller.
The system controller may be programmed to provide the
following modes of arbitration:
Round Robin (RRS)
Single Level (SGL)
Priority (PRI)
The system controller provides a SYSCLK driver, IACK* daisy-chain
driver, and a VMEbus access timeout timer. The system controller
also provides an arbitration timeout if BBSY* is not seen within
a specified period after a BGOUT* signal is issued. This period is
programmable for 16 or 256 μs.
VMEbus Requester: The microprocessor can request and gain
control of the bus using any of the VMEbus request lines (BR3* to
BR0*) under software control. The requester can be programmed
to operate in any of the following modes:
Release-On-Request (ROR)
Release-When-Done (RWD)
VMEbus Capture and Hold (BCAP)
Mailboxes: The VMEbus interface provides four 32-bit mailboxes,
which are accessible from both the microprocessor and the
VMEbus providing interprocessor communication. The mailboxes
have the ability to interrupt the microprocessor when accessed
by VMEbus.
Interrupt Handler: The interrupt handler monitors, and can be
programmed to respond to any or all VMEbus IRQ* lines. All
normal-process VMEbus-related interrupts can be mapped to PCI
INTA# or SERR# interrupts. These include:
Mailbox interrupts
VMEbus interrupts
VMEbus interrupter IACK cycle (acknowledgment of
VMIVME-7750 VMEbus-issued interrupts)
