    • A method for controlling communication on a bus connecting a first processor, a second processor, and a device. The method transmits a first control signal from the first processor to the second processor via a control signal line, causing a bus connection of the second processor to enter a high-impedance state, transfers data between the device and the first processor via the bus, then setting a bus connection of the first processor to the high-impedance state, and transmits a second control signal from the first processor to the second processor via the control signal line, causing the bus connection of the second processor to exit the high-impedance state.
    • 一种用于控制连接第一处理器,第二处理器和设备的总线上的通信的方法。 该方法经由控制信号线将第一控制信号从第一处理器发送到第二处理器,使得第二处理器的总线连接进入高阻态,经由总线在设备和第一处理器之间传送数据, 然后将第一处理器的总线连接设置为高阻抗状态,并且经由控制信号线将第二控制信号从第一处理器发送到第二处理器,使得第二处理器的总线连接退出高阻抗 州。
