    VME bus transferring system broadcasting modifiers to multiple devices and the multiple devices simultaneously receiving data synchronously to the modifiers without acknowledging the modifiers 失效
    VME总线将系统广播修改器传输到多个设备，并且多个设备同时接收数据到修改器的数据，而无需确认修改器

    摘要： A method for synchronous broadcasting of multiple bytes over a VME bus broadcasts multiple bytes of data across the VME bus using hardware which interfaces between the bus and attached devices. An VME address modifier code is used to identify the type of broadcast and is sent by a master device, without requiring any response from the slave devices. In a first type of broadcast an address location is transmitted over the address bus and a data message is transmitted over the data bus. In a second type of broadcast data messages are transmitted over both the data and the address buses. Multiple broadcast cycles are used to transmit the desired amount of data. An address strobe qualifies the address and data buses for a message broadcast cycle and is used by the receiving slave to clock in the message.

    摘要翻译： 一种用于通过VME总线同步广播多个字节的方法通过使用总线和附加设备之间的接口的硬件在VME总线上广播多个字节的数据。 VME地址修改码用于标识广播的类型并由主设备发送，而不需要来自从设备的任何响应。 在第一类广播中，通过地址总线传送地址位置，并通过数据总线发送数据消息。 在第二种类型的广播数据消息通过数据和地址总线发送。 使用多个广播周期来传送期望的数据量。 地址选通符限定了消息广播周期的地址和数据总线，并且被接收从机用于消息中的时钟。
