Abstract (en)
[origin: DE19623668C1] The arrangement includes a bus coupler (15a, 15c) which joins a system bus (10), having at least one local bus (14a, 14c), to the processors (16a.. d), having buffer memories, which contain buffer lines (17a..d ). The bus coupler includes arrangements, which copy the coherence protocol of the system bus (10) onto the local bus (14a, 14c). The arrangements contain at least one intervention register (21) and at least one write register (22) for buffer lines, which are respectively connected with the local bus (16a.. d) for reading and with the system bus (10) for writing. The write register is also connected with the local bus in such way, that the content of the write register is transferable into the intervention register (21), during one, the content the write register, concerning intervention.
