Abstract
The invention provides a bus control method. According to the method, an enable signal is transmitted between slave devices and a master device on the basis of a signal transmission lines independent of a transmission task signal bus, and the operation states of the slave devices are adjusted through combination of the enable signal and the current operation states of the slave devices so that the slave devices keep working or perform state switching. Since the independent signal transmission lines are arranged between the master device and the slave devices, the enable signal can be directly transmitted to a target slave device, and the target slave device does not need to monitor the signaling transmission on the bus in real time, but only needs to make a judgment according to the received enable signal and the self-operating state and then gives a response. Therefore, the slave devices, which do not need to respond the enable signal, can neglect or do not respond the enable signal according to the self-operating states so as avoid useless monitoring; therefore, the power consumption of the slave devices is reduced and the overall power consumption of a bus system comprising the master device and the slave devices is reduced.
