VME7740-841 processor

Description

VMIC’s VME7740-841 is a complete Pentium III processor-based computer with the
additional benefits of single Eurocard construction and full compatibility with the
VMEbus Specification Rev. C.1. The VMIVME-7740, with advanced VMEbus interface
and RAM that is dual-ported to the VMEbus, is ideal for multiprocessor applications.
The single CPU board functions as a standard PC/AT, executing a PC/AT-type
power-on self-test, then boots up MS-DOS, Windows 95, Windows NT, or any other
PC compatible operating system. The standard PC features of the VMIVME-7740 are
discussed in Chapter 3 of this manual.
The VMIVME-7740 also operates as a VMEbus controller and interacts with other
VMEbus modules via the on-board PCI-to-VMEbus bridge and the Endian conversion
hardware.
The VMIVME-7740 may be accessed as a VMEbus slave board. The VMEbus functions
are available by programming the VMIVME-7740’s PCI-to-VMEbus bridge according
to the references defined in this volume and/or in the second volume dedicated to the
optional PCI-to-VMEbus interface board titled: VMIVME-7740 Tundra Universe
II™-Based VMEbus Interface Product Manual (document No. 500-007740-001).
Throughout this manual, all references to the Universe II refer to the Universe IIB.
The VMIVME-7740 programmer may quickly and easily control all the VMEbus
functions simply by linking to a library of VMEbus interrupt and control functions.
This library is available with VMIC’s VMISFT-9420 IOWorks Access software for
Windows NT users.
The VMIVME-7740 also provides capabilities beyond the features of a typical
PC/AT-compatible SBC including general-purpose timers, a programmable
Watchdog Timer, a bootable flash disk system, and nonvolatile SRAM. These features
make the unit ideal for embedded applications. These nonstandard PC/AT functions
