标准摘要
[中文适用范围]: VMEbus 规范定义了一个接口系统,用于在紧密耦合的硬件配置中互连微处理器、数据存储和外围控制设备。 该系统的设计目标如下: a) 允许 VME 总线上的设备之间进行通信,而不干扰与 VME 总线接口的其他设备的内部活动; b) 规定设计设备所需的电气和机械系统特性,这些设备能够可靠且明确地与连接到 VME 总线的其他设备进行通信; c) 指定精确定义 VME 总线和与其接口的设备之间交互的协议; d) 提供描述系统协议的术语和定义; e) 允许广泛的设计自由度,以便设计者可以优化成本和/或性能而不影响系统兼容性; f) 提供性能主要受设备限制而不是系统接口限制的系统。 [外文原描述]: The VMEbus specification defines an interfacing system used to interconnect microprocessors, data storage and peripheral control devices in a closely-coupled hardware configuration. Its objectives include allowing communication between devices on the VMEbus without disturbing the internal activities of other devices on the VMEbus, allowing a broad range of design latitude so that the designer can optimize cost and/or performance without affecting system compatibility, and providing a system where performance is primarily device-limited rather than system-interface-limited. Note that this publication is available not in paper form but as a CD-ROM.
