Bus control unit for assisted program flow monitoring in star topologies, associated program flow monitoring system and method for program flow monitoring

摘要

The present invention relates to a bus control unit for supporting data flow monitoring in a star topology, wherein an address comparator a target address, which is present at a bus interface, with a monitoring address area and deactivates an associated data processing unit connected to a monitoring bus interface and mirror-images the data stream to the monitoring bus interface if the target address which is present does not match the monitoring address area.
