Step S63: the source equipment detects whether the handshake with the destination equipment is successful; if successful, executing S64, otherwise ending the flow;
in the embodiment of the invention, the source device can determine whether the handshaking between the SRIO interface and the SRIO interface of the source device is successful by reading the status register of the SRIO interface of the source device;
step S64: and the source equipment acquires the address information of the SRIO interface in the destination equipment and stores the address information in the address table of the destination equipment.
In the embodiment of the present invention, the address information of the SRIO interface in the destination device may be specifically read through an Nread command.
Through the above process, the source device may communicate with the destination device, and in the operation stage of the source device, if the address of the SRIO interface of the destination device is changed, as shown in fig. 7, the destination device may specifically change the address of the SRIO interface in the destination device address table in the source device in the following manner:

in the embodiment of the present invention, the source device may specifically receive the broadcast message in a polling or interrupt manner;
step S82: the source device judges whether the broadcast message is used for updating the address table of the destination device; if yes, go to step S83; otherwise, ending the flow;
since the doorbell message is generally applied to an interrupt event in practical applications, in the embodiment of the present invention, when the source device uses the doorbell message as a broadcast message, a flag for updating the address table generally needs to be set in the doorbell message; the source device needs to analyze the broadcast message and check whether the broadcast message has a mark for updating the address table or not when receiving the broadcast message; the source device may determine that the broadcast message is for updating the destination device address table if the broadcast message has an identification for updating the address table, and otherwise, may determine that the broadcast message is not for updating the destination device address table.
Step S83: the source equipment reads the modified configuration information from the preset address by using an Nread command;
step S84: the source device updates the destination device address table.
In the embodiment of the invention, in the system operation stage, the DirectIO memory allocation of a certain SRIO endpoint can be dynamically modified according to the system operation requirement, so that the risk of modifying the whole subversion of the system caused by modifying the DirectIO memory allocation can be avoided.
