VMIVME7740-841 基于Pentium III处理器的单板VMEbus SBC

VMIC的VMIVME-7740是一款完整的基于奔腾III处理器的计算机，具有单欧洲卡结构的额外优势，并完全兼容VMEbus规范Rev. C.1。VMIVME-7740具有先进的VMEbus接口和双端口到VMEbus的RAM，是多处理器应用的理想选择。
单个CPU板作为标准的PC/AT，执行PC/AT类型的上电自检，然后启动MS-DOS, Windows 95, Windows NT或任何其他PC兼容的操作系统。本手册第3章讨论了VMIVME-7740的标准PC功能。
VMIVME-7740还可作为VMEbus控制器，并通过板载PCI-to-VMEbus桥接和Endian转换硬件与其他VMEbus模块进行交互。
VMIVME-7740可以作为VMEbus备板访问。VMEbus功能可通过编程VMIVME-7740的PCI-to-VMEbus桥根据参考定义在本卷和/或在第二卷专用于可选的PCI-to-VMEbus接口板标题:VMIVME-7740 Tundra Universe II™基于VMEbus接口产品手册(文档号500-007740-001)。
在本手册中，所有提到宇宙II的地方都指的是宇宙IIB。
VMIVME-7740程序员可以简单地通过链接到VMEbus中断和控制函数库来快速轻松地控制所有VMEbus函数。
该库可与VMIC的VMISFT-9420 IOWorks Access软件一起使用，适用于Windows NT用户。
VMIVME-7740还提供了典型的PC/ at兼容SBC功能之外的功能，包括通用定时器、可编程看门狗定时器、可启动闪存盘系统和非易失性SRAM。这些特性使该单元成为嵌入式应用的理想选择。这些非标准的PC/AT功能将在本手册的第4章中讨论。

VMIVME7740-841

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.
