Abstract
To increase an overall access speed and a performance of a bus system, in the present disclosure, a master device is designed to use a clock signal with different clock frequencies to address slave devices and read/write data from/to the slave devices. In an address phase, a first operating frequency which the master device can successfully address the slave devices is used as a clock frequency of the clock signal for addressing. In a read/write phase, a minimum one (i.e., a second operating frequency) of multiple working frequencies of the slave devices is used as the clock frequency of the clock signal for reading/writing, wherein the master device is connected to the slave devices via a bus. The working frequency of the slave device means a maximum clock frequency supported by the slave device.
