INTEGRATED CIRCUIT HAVING A BUS NETWORK, AND METHOD FOR THE INTEGRATED CIRCUIT

摘要

A bus network passes pending messages from bus interface to bus interface until they are downloaded at a target bus interface by a target device connected to the target bus interface. The messages are tagged with at least one download control bit. The download control bit has a priority state indicating that a message has already passed the target bus interface at least once without being downloaded. When controlling selection of messages for downloading by the target device, the target bus interface selects messages with the download control bit in the priority state with a greater probability than messages not having a download control bit in the priority state.
