VMIVME-7740 Abaco系统/ VMIC

VMIC’s VMIVME-7740 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 are discussed in Chapter 4 of this manual.
