A method and system for a coherence protocol for buffer memories which covers interventions in multiprocessor data processing units, wherein a bus coupler maps the coherence protocol of a system bus onto a local bus and, in the event that an intervention relates to a buffer line which is in the write register, transfer this buffer line from the write register via the local bus to the intervention register.
