发明名称 System bus interface controlling at least one slave device by exchanging three control signals
摘要 A slave device, connected directly to a system bus, which system bus requests the execution of a complex communication protocol, is controlled by another device, connected to the system bus, which identifies the slave device as the target of a transaction on the system bus, executes the communication protocol and sends to the slave device through an auxiliary interface a first identification signal, a second signal for instructing execution of the transaction, and receives from the slave device, through the auxiliary interface, a transaction executed signal. In this way the interface logic of the slave device is reduced to the minimum since the slave device is not required to execute the communication protocol.
